In this episode, Mark sits down with Sue-Ching Yeoh, an AHPRA-registered Oral Medicine Specialist with clinical appointments at Royal Prince Alfred Hospital and Chris O’Brien Lifehouse, and an academic role at the University of Sydney. This conversation goes far beyond dentistry. A/Prof Yeoh explains how the mouth acts as an early warning system for systemic disease, including autoimmune conditions, cancer, HPV, and chronic inflammation. She breaks down what gum disease actually is, why bad breath is often a medical issue rather than a hygiene one, and how lifestyle, genetics, vaping, smoking, and even social media trends are quietly damaging oral health

They also cover practical, no-nonsense advice most people never hear:

How to properly self-check your mouth
The truth about tongue cleaning, salt water rinses, whitening, and sensitivity
What tooth wear says about stress, nerve health, and aging
When cosmetic treatments help and when they mask deeper problems
Why early detection in oral health can be life-saving
