Which dental condition can contribute to TMJ disorders by affecting occlusion?

Explanation:
Occlusion is how upper and lower teeth contact when the jaw closes. When teeth are missing, adjacent teeth drift into the gap and opposing teeth may over-erupt, creating new bite relations. This shifts how forces are distributed across the dentition and changes condylar loading, which can trigger TMJ pain, joint sounds, and limited movement. A cracked tooth tends to cause bite interference only locally rather than a widespread change in occlusion. Bruxism can produce occlusal wear and joint stress, but the structural disruption from tooth loss is the classic way occlusion is altered. Fluoride varnish has no impact on occlusion or TMJ risk.
