I'm Roman Mars. The walk begins at the parking lot at the end of the road. The site isn't much to speak of, just a sprawling expanse of asphalt peppered with cars. Over a million people come here every year to embark on a kind of pilgrimage. They're here to cross the border.
Narrator / Roman Mars
We are getting ready to go to Mexico this morning. Yes, one more time. So we shall see what the rest of the day hold. There are hundreds of videos online documenting this experience. Watch as many as I did, and they all start to meld together.
Lasha Madonn
That's 99 PI producer Basha Madonn.
Narrator / Roman Mars
Some people seem nervous in the videos. Others are more excited. Many will turn to their imagined audience behind the camera and speak in a reassuring tone. You see that American flag up there, y'? All? This is one of the safest crossings there is. And it's not scary. I promise you, it is not scary. Everyone here is headed to the same town in Mexico. It's called Los Algodones. And it's a place where for decades, Americans have roamed the streets. They come here in desperate search of something. They need something that's almost impossible to find. Where they live. They're looking for a dentist, one that they can afford.
Lasha Madonn
Every day, thousands of people, mostly American, mostly white, and mostly retired, come to this town looking for relief from the turmoil in their mouths. Here, dental care costs up to 80% less than what it might cost in the U.S. dental tourism to Los Algodones is so common that many call this place Molar City. Today there are nearly 1,000 dentists in this 7,000 person town, and 98% of those in the patient's chair traveled here from outside Mexico. Lasha is going to take it from here.
Narrator / Roman Mars
Watch any one of these YouTube videos and you'll see how a trip to Molar City is made easy for an American. For decades, this crossing didn't even require a passport. In one video, a retired couple arrives at Arizona's edge. They do a 360 displaying the massive lot where they've just parked. We love Mexico, they say, emphatically talking to the camera. The camera then pans to show the rust colored border wall in front of them. That corrugated monstrosity, they Marvel. Then a U.S. border Patrol vehicle starts driving past the screen. On guard, it seems for anyone trying to CR in the opposite direction to this, the camera woman speaks again, as if she's talking directly to Border Patrol. Get em boys, she says. Then they begin their walk into Mexico. In Los Algodones, there are dense clusters of medical offices and a canopy of billboards. Above them, vendors are set up on sidewalks where they sell handmade goods and kitschy souvenirs, like this one graphic tee that says, keep calm. You're on the fun side of Trump's wall. And then there are the street promoters, people who are stationed at almost every street corner, each of them competing for superlatives. The best deal, the quickest appointment, the most popular clinic in town. In Molar City, a street promoter is the first person a tourist will encounter.
Dr. Jesus Medina
Good morning buddy.
Narrator / Roman Mars
What is it?
Alberto (Street Promoter)
Dental pharmacy glasses.
Dr. Jesus Medina
I got dental promotions.
Narrator / Roman Mars
Some promoters try to lure people in with discounts. Others vie for attention in more creative ways, like dressing up in a full body tooth costume and waving a sign. Then there's Alberto, a street promoter who takes a different approach altogether. He tries to attract customers with humor.
Alberto (Street Promoter)
I'm always trying to make stuff funny, you know, make them laugh like a comedian, almost make them relax just for that second.
Narrator / Roman Mars
Alberto is employed by a couple clinics in town. He's assigned to a specific street corner where he stands all day and tries to make his commissions.
Alberto (Street Promoter)
Since I'm like at a corner, I have a lot of people that pass by me, so I talk to everybody eight hours after I'm over. From early in the morning, I'm talking and talking until I don't stop talking all day.
Narrator / Roman Mars
He told me that street promoters can also get a little territorial with each other because they're all vying for the attention of the same Americans who walk into town.
Alberto (Street Promoter)
You don't need appointment. My doctor's open right now.
Narrator / Roman Mars
You get that service right away.
Alberto (Street Promoter)
We're not working with appointment.
Dr. Jesus Medina
Good morning, buddy.
Alberto (Street Promoter)
What is it?
Narrator / Roman Mars
Dental pharmacy classes.
Alberto (Street Promoter)
You know what I did all day? I taught non stuff all day, and I still had energy left.
Narrator / Roman Mars
Alberto loves to talk. When I told him I wanted to talk about Molar City, he was like, how much time do you have? He told me how one time he was on the phone with a girlfriend for a whole 24 hours, standing at a payphone for an entire day, just talking. From this anecdote alone, I got the impression that Alberto was probably good at his job, or at least that he had the stamina to endure it. Well, maybe let's not aim for 24 hours, but I'd love to chat a little bit. Alberto grew up nearby, and over the course of his life, he's seen how Los Algodones transformed into Molar City.
Alberto (Street Promoter)
Being in the border, we have this. We have America. America is very influential. America really affects everything that happens to the people right here.
Narrator / Roman Mars
Los Algodones has built itself up to serve the dental needs of Americans and Canadians. And the town has become wildly successful in this goal. But Algodones went through many reinventions before it became more. And I wanted to understand how it all happened and why. Los Algodones means cotton in plural. And that's because commercial cotton farming is what this land was once known for, back when it was still vibrant and green. Then a series of policy changes depleted the soil and dammed the flow of the Colorado river into Mexico. By the 60s, riverbeds were drying up and crops were struggling. But many Mexican border towns have long had another thriving business, booze. And after the farming industry crumbled, that's what Los Algodones relied on. At one point, the town had 48 bars. American soldiers living on military bases in Yuma, Arizona, were regulars. Alberto spent his childhood in Yuma, too.
Alberto (Street Promoter)
Yeah, we go to Aguadones to get drunk, but yeah, I just. That's what Algodones has been to me from the beginning. It was this little town.
Dr. Jesus Medina
Algodone was a very small town with lots of cantinas, and used to come people from Yuma to dance in the cantinas or drink.
Narrator / Roman Mars
This is Dr. Jesus Medina. He moved to town fresh out of med school in 1973, and he's been working here as a doctor ever since. Although he seems to be perpetually on the brink of retirement.
Dr. Jesus Medina
I think one day I have to retire and My sons tell me when you're going to retire.
Lasha Madonn
Why?
Dr. Jesus Medina
I'm too young to retire.
Narrator / Roman Mars
Dr. Medina first learned about Los Algodones from his brother in law, Dr. Bernardo Magagna, who's often described as the godfather of Molar City.
Dr. Jesus Medina
He was the first dentist from this town.
Narrator / Roman Mars
You know, Magania's now in his 80s. He is retired and didn't want to be interviewed. But Medina told me about how his brother in law, Maganya, first had this vision to transform the town into a dental mecca. Back in the 60s, Maganya and Medina were living together in a City about 25 miles from Algodones. Maganya was a young dentist looking for a place to set up his private practice. At the time, he was working for someone who already had a few American patients, patients who likely lived in the south and would cross into Mexico to take advantage of lower prices.
Dr. Jesus Medina
Ladsem start to tell about Algodones, says, why you don't move to Algodones? Because Algodones is four minutes from Yuma. Says if you go there, you're going to have a lot more patience.
Narrator / Roman Mars
At first, Magania was skeptical. He paid Los Algodones a visit, and it was a lot like he expected. A sleepy little place with a lot of mostly drunk people. But many of those drunk people were Americans. Its proximity to the border meant there was already a culture of coming and going. He saw the Americans spending their money at the bars and thought maybe they'd spend money on dentistry too. Magagna knew he could offer them a price lower than what they could get in America.
Dr. Jesus Medina
And my brother in law, he got the idea and says, I'm going to put an office in Aguadones. And he put the office. And he grows so fast and he has so many patients, so many patients.
Narrator / Roman Mars
Magania set up his clinic right across the street from the border crossing. On his first day, he saw nine patients. And for the first three years he was the town's only dentist, sometimes working from 6 in the morning until 11 at night. The demand for health services ended up being so much more than he could handle on his own. So he started asking others to come set up shop, including Dr. Medina.
Dr. Jesus Medina
And then I had the idea to come and practice right here.
Narrator / Roman Mars
Magania helped Medina acquire a small office for his practice.
Dr. Jesus Medina
He gave me a key. He says, take this. What? Go to my office and see. And then I come and I see. He made me a very small office, you know, two rooms, waiting room in the office, to give attention a Table, a desk. And that was my first, my first practice office I have, you know.
Narrator / Roman Mars
Medina remembers those early days with amazement. Once he stepped out of his office to see a line of people, Americans, all waiting for an appointment with him. He wasn't even taking appointments. He says the demand was immediate.
Dr. Jesus Medina
And I start to work and I start to see American people, you know, hard time because I don't speak too much English. By the we, I don't kill nobody, you know.
Narrator / Roman Mars
Magania and Medina were treating patients who would talk about their struggles with healthcare. In America. For most Americans, dental care has always been out of reach. Early dentistry was considered more of a craftsman's trade. Dental work was performed by barbers and blacksmiths, people who were considered quacks by the larger medical field. And ever since then, dentistry and general medicine have fought hard to keep themselves separate. Cut to today, and dental and healthcare are still separated. They have separate insurances, separate teaching schools, separate medical records even. It's as if matters of the mouth are separate from the body. But of course, they're not. Every year, hundreds of thousands of Americans end up in emergency rooms for something like a toothache, something that could have been treated in a dental office. But most ERs don't have on call dentists. So often these patients are sent home with painkillers and are told to go visit their dentist. But a lot of these people don't have dentists. Or if they do, the cost for a visit is impossibly high. And yet people are held personally accountable for the state of their teeth in ways that they're not held accountable for many other health conditions. Poor dental care can be both life threatening and humiliating, as if unhealthy teeth are a failure of individual responsibility rather than the symptom of a broken system. In Algodones, Dr. Magagna saw the state of dental care in America as an opportunity to turn this small Mexican border town into a place for full of dental services catered to desperate Americans and Canadians looking for deep discounts. But the town was still mostly strip clubs and bars, and he felt like that was holding them back. So in 1980, Magagna became mayor, although the technically accurate term is municipal delegate. As municipal delegate, Magagna shuttered most of the cantinas. It was his first major step in transforming Algodones into Molar City. Year after year, the same buildings that house those cantinas gave way to more clinics and pharmacies.
Dr. Jesus Medina
In cantinas I don't have, there is no more. Only one or two. In Algodones you know, but they disappear almost, you know, if we drink, we drink at home. All cantinas are dental offices now.
Narrator / Roman Mars
Magagna helped transform the town in other ways, too. He opened a middle school, a high school and a dental school. And Dr. Medina, like his brother in law, also got involved in town leadership. He coached the local sports teams, and he became the town's first official delegate of tourism.
Dr. Jesus Medina
When I come, we make the revolution right here, you know.
Narrator / Roman Mars
More and more healthcare professionals were migrating to Algodones. And among Americans, knowledge of the town's services was spreading, although mostly by word of mouth. Still, Dr. Medina was looking for a way to take Algodones to the next level. And so he decided to attract people to their reformed party town by throwing a giant party. A party specifically for snowbirds, a term for retired Americans and Canadians who migrate south every year following the sun. Come on over, medina advertised. We'll have free margaritas, free Viagra, discounted root canals. When kind of did you start this?
Dr. Jesus Medina
Wait a minute, a minute, because I.
Alberto (Street Promoter)
Forget.
Dr. Jesus Medina
Right here is when they give me the position, you know, in the.
Narrator / Roman Mars
Newspaper of Mexicali, Dr. Medina's sitting in his office flipping through an old photo album that he's holding up to our zoom screen. It's full of newspaper clippings and pictures of all the parties he threw over the years. His first One was in 1987. Seven thousand tourists showed up in the photos. They're all crammed into the town's four square blocks. Many are holding red solo cups.
Dr. Jesus Medina
This was my first party. Look at American people. How I doing? Just in the street, you know, I don't have places to do it.
Narrator / Roman Mars
Medina flips through the book fondly, as if he's cooing at baby photos.
Dr. Jesus Medina
And that's the way Algodones start, you know, with that. And like this, you can see all my book is full of parties, you know, till do I go and everything, you know. Well, it's all my life in this book, you know.
Narrator / Roman Mars
It'S clear that Medina put his heart into these parties, into making the town grow the way it did. He convinced his neighbors to cook enough food to feed thousands for free. He hired a mariachi band and converted an old boxing ring into a stage. And the Americans had a great time. Medina made sure the margaritas were strong.
Dr. Jesus Medina
And they was drunk like crazy. You know, the American Customs told me, Dr. Medina, why you kid to those guys, why they cross right here? They don't want to show the papers. They tell us, son of a bitch. They was very drunk.
Narrator / Roman Mars
Year after year, Los Algodones would continue to throw parties like that first one. Americans would return home. Talk of the tacos, the town, their teeth. What was once a town of about 750 when Magania first arrived, is now crammed with clinics, hotels, restaurants, and pharmacies. Today, young dentists and souvenir vendors from all over Mexico continue to migrate to town in hopes of finding stable work. And the tourists keep coming in droves.
Dr. Jesus Medina
In winter, it's too much people and they make lines and that's. They're uncomfortable for them, but they don't care. They make the lies, you know, and they still coming because they find dental service is good, a good price and everything, and very handsome doctors. We live from the tourists, you know.
Narrator / Roman Mars
We live from the tourists. It's a sentiment I heard from everyone in town. Teenagers will run to the border after school to sell trinkets to people waiting in line to go home. Women will walk up and down the line selling handmade sweaters and hot meals. And on the American side, the Quecsan tribe manages a casino resort. It's a popular spot for dental tourists who try their hand at the slot machines in between appointments.
Alberto (Street Promoter)
I think Agradones is a good town. It's become a better town than it was before. You know, we really don't have a lot of, like, serenic views or like anything touristic, but the people are really like. They're really like hard working people, and they're also. They like to party, you know, like they have good times also.
Narrator / Roman Mars
Street promoter Alberto moved back to the area eight years ago, in part to be closer to his family after a road accident in Cancun made it difficult for him to walk. He told me he gets discounted dental care from the clinics that employ him, but he's been putting off amputating his leg for years. Because of the cost of surgery promoters.
Alberto (Street Promoter)
We vary anywhere from $120 to. Some of us. Some of us are making like five or eight hundred dollars a week.
Narrator / Roman Mars
I asked Alberto what he thought about the town's transformation into Molar City.
Alberto (Street Promoter)
I think Dano has helped Algodones a lot, but I think people just make their money and they go somewhere else, you know, they go live it up somewhere else.
Narrator / Roman Mars
Hmm.
Alberto (Street Promoter)
Because a lot of doctors have become millionaires.
Narrator / Roman Mars
Many of those original dentists live in mansions complete with indoor courtyards and pools. In addition to their dental practice, certain families in town own many of the hotels, restaurants, and pharmacies here. But zoom out of the town center and you'll see mostly unpaved roads and humble homes. There's this 18th century paleontologist, Georges Cuvier. He has this famous quote about teeth. Show me your teeth, he said, and I will tell you who you are. It's true that from teeth alone, a dental anthropologist can gather all sorts of information. They can decipher migration patterns and cultural norms. They can tell if you ate with your fingers or if you endured famine. Our teeth are biographies. They hold facts about ourselves, facts we may not even recognize while we're alive. I'm curious how you would describe your relationship to your teeth.
Alberto (Street Promoter)
You know, my relationship with my, with my teeth was, you know, I didn't really take time on a daily basis to have good dental care. I haven't truly smiled in probably 10 years.
Narrator / Roman Mars
This is Jeff Jackson. He's a retired veteran in his 60s. Jeff and his wife live in their RV, which is parked in Nevada for most of the year. Over the last couple years, Jeff started losing more and more teeth. By the time he made the decision for implants, he had 13 teeth left.
Alberto (Street Promoter)
Both my wife and I are both waiting to get those permanent teeth in. Yeah, it's just, it's, it's gonna be a fun time. Go down there and get them in and be able to enjoy it.
Narrator / Roman Mars
I spoke to Jeff after his second trip to Molar City. He was planning to go back a third time to complete what's called a full mouth restoration, which is one of the more popular treatments in town.
Alberto (Street Promoter)
Yeah, you understand why people go through it. I was like, you know, I'm just going to be an ugly old dude anyway. But the confidence booster and not having to sell my house to do it.
Narrator / Roman Mars
Jeff isn't eligible for Medicare. He makes too much money for Medicaid, and he couldn't find a private insurance plan with a premium he could afford. A dentist in Nevada put together a price tag of about $50,000. In Los Algodones, he found the same treatment for less than 20,000 on top of the implants themselves. That price included getting his remaining teeth pulled, the cost of his pain medication and his hotel stay. Mexican dental work is less expensive for a couple reasons. Labor and real estate in Mexico costs a lot less than in the US and dental school is heavily subsidized, meaning fewer dentists. Graduate school. With the kind of colossal debt that's rampant in the US and in Mexico, dentists don't need to get malpractice insurance. Still, it's not as though Mexican dentistry is affordable to all Mexicans. Only 48% of Mexicans nationwide who are in need of oral health care are able to receive it. But to the average American, it's a discount worth traveling for. And this trend might increase. By 2060, the number of Americans over 65 will practically double. And the US will see an exploding need for all kinds of health care services in a system that won't be able to support all of its people. People like Jeff. I'm just curious if you have any, if you have any thoughts or opinions on healthcare access to healthcare in the U.S. you know, from, from your perspective, I mean, there's clearly a problem, right?
Alberto (Street Promoter)
I am a dive in the wool capitalist kind of guy and so I don't really buy off on socialized medicine. But we have to bring down costs. You have, you know, millions of people that can't afford to health insurance to.
Narrator / Roman Mars
Jeff Mohler City might be a solution, but dental tourism is also a measurement of the problem. It shows us the lengths people must go to seek an end to their pain.

Narrator / Roman Mars
On a typical day, dentist Myra Jimenez is buzzing around her clinic. Mayra moved to Algodones from Guadalajara two decades ago. She says her early memories there are a blur, mostly because she was so busy working. I mean, skipping meals, skipping everything. I mean, there were so many people. I did up to a hundred crowns in a single day. I was a machine. Myra told me that in those days the streets were so packed with Americans that you couldn't get through. She was always working all day, I'm telling you, from 8 in the morning to 10pm this is Myra's daughter, Rennie, who works in her mom's clinic. Rennie grew up in this clinic. She uses the words waiting room and living room interchangeably. Like living rooms. Like the waiting areas would be packed with people. Just packed. And I remember I had a ride that would drop me off at the border and one of my mom's workers would pick me up walking. So I'd come back walking to the office. And I remember my mom didn't know how to speak English. And so I remember sitting in the living room in the waiting area with patients from Canada, from Utah, from Texas, from California, and all the patients helping me do my homework every single day. Myra never expected to move up to Los Algodones to raise her kids on the border. Her first impression was that the town was arid and boring. But Myra likes having Americans as patients. She says that they're especially grateful. Before moving to town, Myra had never met people so excited to be seeing a dentist. And what I love most is that the Americans always treated us very well. They were very Grateful patients and you became friends with them. I love that. I remember being a little kid and my mom would come home with patience to my house. Oh, this is so and so. And they're going to be eating dinner with us. And I'm like, who are these people? Myra and Rennie talked a lot about this sense of community fostered between dentist and patient. But Myra also has concerns about the industry. In fact, there's one thing that it seems like almost everyone is constantly worried that the town stays safe, and more importantly, that the town is perceived as safe. Violence and organized crime is a real problem in the Mexican borderlands, but medical tourists are rarely targeted. Still, one dental coordinator told me that trying to quell concerns about safety is a major part of her job. She told me that her American clients bring it up all the time. I think because Mexico has, you know, a bad reputation in the US and everybody thinking coming into Mexico is dangerous. I've had people thinking that, oh, we're gonna come to Mexico and we're gonna be waiting here with guns and stuff like that. But people have told you that, yeah, they're like, oh, I thought it was gonna be the cartel outside, and. And I'm like, no, it's very safe, and they're very scared. But I think it's more because of the news more than real incidents of violence and crime. People working in Algodones are concerned about how Mexico is portrayed in American media. Que la valacera que tevana rubar. The news comes out that there's going to be a shootout, that they're going to kidnap you, that if you cross to Mexico, you're in danger, that your life is in danger. Yes, I think that affect us.
Dr. Jesus Medina
I think most people, they're a little scared to come to Mexico because the histories they hear in United States, you know, who they can stool them right here or they can do something. Shotguns and things like that. Mafia guys, whatever, you know, Los Agrones.
Narrator / Roman Mars
Itself is actually a pretty safe place to visit. But still, the town works so hard to correct the narrative that many Americans have about Mexico. Their livelihoods depend on it.
Christina Adams
The industry is having to put a lot of effort and spend a lot of money and make lower profits than they might otherwise if they didn't have to put so much effort into dealing with that narrative or those prejudice assumptions about Mexico.
Narrator / Roman Mars
This is Christina Adams. Christina's a public health researcher who studied the ethics of dental tourism in Los Algodones. She wanted to know how the industry might be affecting locals.
Christina Adams
I think it's completely normal for someone leaving their home country and accessing healthcare to be questioning, you know, is this safe? What are the standards of care in this different country? And then I think there's another layer on top of that where I think they're also trying to combat really prejudiced assumptions about Mexico as much as possible. That it's, you know, a country from the global south, that it's underdeveloped or even undeveloped, that there's no way the standards could be as high of quality in a place like Mexico.
Narrator / Roman Mars
Cristina says that clinics in Algodones employ certain strategies to maintain a positive reputation with tourists. Some clinics will pay medical tourism companies in other countries to act as a middleman between patient and clinic. Many of these companies are based in Europe, and they'll put Mexican clinics through a vetting process to prove their legitimacy to a non Mexican clientele. When making interior design choices, clinics might consider an American aesthetic, whatever that means. The goal is to make sure the image of Mexican dental care is squeaky clean, Sometimes quite literally. Cristina remembers being hit by the intense smell of sanitizer when she walked into the many clinics in town.
Christina Adams
It was overwhelming. Sometimes walking into a dental clinic, just the smell of sanitization, like, it feels like above and beyond anything I'd ever experienced myself walking into healthcare spaces. Like, they're really trying to make sure you smell and notice right away, like, this is clean.
Narrator / Roman Mars
All this effort is to make Los Algodones feel safe and comfortable, Relatable, even. And so there are ways in which the town has worked to play up its American ness by minimizing its Mexicanness.
Christina Adams
I definitely remember this sense of, like, staff being told to minimize their Mexican accents because that would help people, tourists, feel more comfortable.
Narrator / Roman Mars
Christina's research also found that some clinics would hire someone who speaks American English to just sit in the waiting room. The idea being that their presence might help nervous Americans feel more at ease. It seems like everyone who lives and works in town has their own strategy to calm anxious American nerves. One local dental tourism company uses a camera to occasionally livestream the border crossing From a bird's eye view. These videos exist almost as if to say, see? It's so uneventful here. Boring, in fact. Safe. Back when Dr. Jesus Medina was head of the tourism department in the 80s, he developed his own strategy to make skeptical US tourists feel comfortable in a Mexican dental clinic. Clinic. He created a complaint office, a place tourists could go if they felt like they were being scammed. He called it the office of defense of the tourists.
Dr. Jesus Medina
That way, if one Mexican doctor do a bad job to one of the patients, they can go to that office, and then we call the doctor and we make them give the money back to the patients.
Narrator / Roman Mars
The office functioned like an amateur quality courtroom, and Medina enlisted Dr. Magana as the judge. Magana would inspect the dental work of other Mexican dentists, occasionally calling the police in for backup.
Dr. Jesus Medina
It was very hard. You know, we seen the police that comes there, he says, and Maranha says, your work is not good. You have to give the money back to the lady.

Police in Los Algodones exist to protect the industry and to make tourists feel safe. There's an old promotional video for Moler City still up on YouTube. It's from 12 years ago, and it's less than a minute long. In the clip, a police officer does a salsa twirl with an elderly white woman. The video is titled All Tourists are Safe and Fun in Los Lagodones.

There's parties, there's fun, there's bars, there's cheap food and drinks, there's dental care, there's a ton of pharmaceuticals. And the police are watching. If there's any sense of, like, any trouble brewing, police will be very much on it.
Narrator / Roman Mars
Police might help tourists feel safe, but for locals, especially low wage workers like street vendors and promoters, the police ensure that their movements are more tightly controlled. Remember those famous welcome parties, the ones that Dr. Medina started in the 80s? A lot of locals aren't invited. In fact, they're explicitly told to stay away.
Christina Adams
There's a lot of expectations around where people are allowed to be on those days. Definitely do not show up at the party unless you're helping to work there. And so on a day like the welcome party, that involves sort of restricting the movement of other folks who live there and making sure that they're only seeing and experiencing what the sort of town elites want them to see and experience to ensure that the reputation of the tourist industry is upheld.

Despite all this effort towards safety, whenever violence does occur anywhere in the border region, it can have major ripple effects on medical tourism. I spoke to someone named David Vquist, a medical tourism researcher who conducted a bunch of surveys on Americans after an incident in 2023 when four American medical tourists were ambushed by a drug cartel and only two of them survived. David was curious about Americans perceived ideas about safety in Mexico and how those ideas might impact their decision to engage in medical tourism there. On one of his surveys, he asked Americans, would you feel safe going to Mexico? And then another question, would you feel safe Going to Cancun. David's research suggested that Americans perceive Mexico and Cancun as two separate places. Cancun is safe. Mexico is not. In a way, I think Los Algodones has achieved that Cancun status. Molar City can exist as a performance for American consumers disembodied from the forces that created it. And about how many people do you think in town have the same kind of job that you do?
Alberto (Street Promoter)
Oh, my competition.
Narrator / Roman Mars
Does it feel like competition?
Alberto (Street Promoter)
Well, I got them all, you know, I got them all pointed out. I got a report on every single one of them. Which one would you want me to start with? I got. My competition's everywhere. Everybody's my competition.
Narrator / Roman Mars
There are dozens of street promoters like Alberto, and because there are so many of them all working on commission, Alberto's success depends on his charisma. He has to give the best performance. And so Alberto has his own strategies to try to stand out and make a good impression. Besides workshopping comedic material on the job, he told me this one other thing. He tends to play up how American he is. It's not a hard thing for him to do because like many people who get grew up along the border, Alberto traveled back and forth a lot. He lived in Arizona, but crossed the border weekly. His English is good. He describes himself as being from the border.
Alberto (Street Promoter)
So I grew up, you know, going to school and then coming down the weekends down to Mexico. And a lot of kids grow up like that because there's a lot of people in Aguadones that were. Oh, I forgot to mention this. I was deported.
Narrator / Roman Mars
Alberto was deported to Mexico in 2010. In fact, I learned that almost all of Moler City's street promoters are deportees. It is, in fact, their American ness, their American English, that makes them ideal candidates for this role.
Alberto (Street Promoter)
Helped me break the ice. It helps me bond with people. Right away, they can tell that I lived in America.
Narrator / Roman Mars
Oh, they bring it up.
Alberto (Street Promoter)
Yeah. They'll say it like that. They'll be like, oh, I can hear you. Oh, yeah, you lived in the States, huh? Like, yes. Got me a little agent occasion over there. So it makes them. Makes me relate to them more and feel more relaxed.
Narrator / Roman Mars
Alberto tells me he'll recognize familiar faces crossing into Mexico from time to time. So and so from high school, his friend's uncle, but he doesn't get to see his family so often. They all live in Arizona and don't like to come visit.
Alberto (Street Promoter)
They really only come when they have to.
Narrator / Roman Mars
Yeah.
Alberto (Street Promoter)
The reason they don't like it is because of the immigration, the way they treat them when they're crossing, they always get harassed. Yeah. When they're going back to America, they get harassed. So they get tired of that.
Narrator / Roman Mars
Los Algodones has long been set up for the benefit of Americans. And the journey Americans take to cross into Molar City has always been a simple one. But of course, the journey in the opposite direction is much more complicated. Can I ask you a question that might sound. I don't know, I don't know how you'll take it, but I'll ask it anyway. You can tell me how you react to it. I've heard from Americans and Canadians, like, people describing what it's like to go down to Los Algodones and people describe just walking freely through the border, like just five minutes, no need to even show a passport. And I'm just curious what that's like for you on your end, knowing that you were kicked out and yet part of your job is to interact daily with, I don't know, hundreds of people who just walk so freely across this border. You know.
Alberto (Street Promoter)
The way I see it is like this. Since I am from the border and we lived in America, we went to school in America, what happens is that when I see people coming from America and I see myself, that I can't go back, which is like literally right there. I can see my mom's house from right here.
Narrator / Roman Mars
Oh, wow.
Alberto (Street Promoter)
That's the hardest thing to see. I see my house, I got the Colorado river and I can literally see the water tank at the reservation. And I can see all the way to the Yuma Hospital on 24th Street. And then I kind of more or less where my mom's house is over here. If I had a drone, I could fly it over there and. And look at, look out.
Narrator / Roman Mars
Yeah.
Alberto (Street Promoter)
That'S how close I am. That's not easy. It's very hard for me.
Narrator / Roman Mars
It's 5am in Algodones. The sky is still dark, not quite sunrise, and Alberto is shuffling around the house getting ready for work. The streets are mostly quiet at this hour. Just the sound of other promoters and vendors setting up setting the stage for Molar City. By 6am he's at his post. The border opens and the Americans descend. They walk in the shadow of the 30 foot wall that divides them, crossing the very threshold Alberto cannot.

This episode of 99% Invisible delves into Los Algodones, Mexico—dubbed “Molar City,” where thousands of Americans and Canadians flock annually for affordable dental care. Once a declining border town reliant on cotton farming and cantinas, Los Algodones has transformed into a dental tourism mecca with almost 1,000 dentists serving mostly foreign patients. The story unpacks the cross-border economies, personal narratives, and dramatic shifts in architecture, culture, and identity that underpin this unique town. The episode also illustrates how the town balances American expectations, Mexican realities, and the contrasting fortunes of those enabling cross-border healthcare.

“You see that American flag up there...This is one of the safest crossings there is…Everyone here is headed to the same town in Mexico. It’s called Los Algodones…They’re looking for a dentist, one they can afford.” — Roman Mars (01:47)

“I’m always trying to make stuff funny…make them relax just for that second.” — Alberto, Street Promoter (05:17)

Quote:
“The confidence booster and not having to sell my house to do it.” — Jeff Jackson (22:04)
Quote:
“Molar City might be a solution, but dental tourism is also a measurement of the problem. It shows us the lengths people must go to seek an end to their pain.” — Roman Mars (24:23)
Quote:
“It was overwhelming…They’re really trying to make sure you smell and notice right away, like, this is clean.” — Christina Adams (33:15)

The episode’s tone is empathetic, investigative, and quietly political, blending humor (via Alberto and local anecdotes) and melancholy (especially around issues of migration, exclusion, and health disparities). Roman Mars and his reporting team combine personal storytelling with historical and systemic context, giving listeners a rich, multidimensional portrait of a town where design, health, migration, and economics collide.
This episode of 99% Invisible offers not only a guided tour through the streets and clinics of Molar City, but also a profound meditation on what happens when design, borders, and necessity shape the places we travel—and the lives of those on each side of the divide.
