Clicks, Locks, and Misalignment - What Your TMJ Disc Is Telling You

Why does your jaw click, pop, or lock? In this episode, Simon explores TMJ disc displacement — a key driver of temporomandibular joint dysfunction.

Learn how the articular disc moves (and misaligns), what causes anterior disc displacement with or without reduction, and how structures like the retrodiscal tissue and lateral pterygoid muscle play a role. We also explore symptoms, treatment options, and the difference between common and rare forms of disc luxation.

If your jaw feels off track, this episode helps you understand why — and what can be done to help.
