You’re doing a routine exam when you spot it – a stained hairline crack snaking across the marginal ridge of a molar. Your patient hasn’t mentioned any symptoms… Yet.

Should you sound the alarm? Monitor and wait? Jump straight to treatment?

Cracked teeth are one of dentistry’s most misunderstood diagnoses. Colleagues debate whether to crown or monitor. And that crack you’re staring at? It could stay dormant for years—or spiral into an extraction by next month.

So what separates the teeth that crack catastrophically from those that quietly hold together?

In this episode, I am joined by final-year dental student Emma to crack the code (pun intended) on cracked tooth syndrome. 

We break down the easy-to-remember “position, force, time” framework to help you spot risk factors before disaster strikes, and share a real-world case of a 19-year-old bruxist whose molar was saved by smart occlusal thinking.

If you’ve ever felt uncertain about diagnosing, explaining, or managing cracked teeth, this episode will change how you think about every suspicious line you see.
