Short Answer
It may be related to jaw joint or chewing-muscle tension, but ear causes should be checked first and the changing conditions should be separated.
How to think about it
If ear fullness changes with opening, chewing, clenching, head position, or morning jaw stiffness after ENT evaluation, jaw movement and chewing-muscle tension can be assessed.
Evidence and limits for this question
What this question checks
This page uses the question "My ear feels full but ENT says it is normal. Could it be related to the jaw?" 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, severe dizziness, or new acute tinnitus should be evaluated by ENT first.
