Short Answer
It can be involved for some people, especially when ear fullness changes with jaw movement or clenching.
How to think about it
Stress can increase tooth contact, clenching, neck tension, and chewing-muscle activity. If ENT warning signs are absent, the repeat pattern can be reviewed alongside jaw and posture factors.

What this question checks
This page uses the question "Ear fullness repeats during stressful periods. Could clenching be involved?" to organize a symptom pattern before assuming a TMJ-related cause.
What to rule out first
Urgent, organ-specific, dental, ENT, neurologic, traumatic, infectious, or breathing-related warning signs should be considered before jaw-related interpretation.
What is reviewed in clinic
Consultation details, symptom timing, jaw movement, chewing muscle tension, bite changes, previous exam results, and recurrence patterns may be reviewed together.
What not to decide from this page
Do not use this page alone to choose a diagnosis, appliance, procedure, medication, or emergency response.
Safety note
Sudden hearing loss, strong dizziness, ear discharge, fever, or one-sided worsening needs ENT evaluation first.
