Short Answer
It can be considered after ENT causes are checked, especially if fullness changes with jaw movement or clenching.
How to think about it
Ear fullness can come from ear, nose, throat, pressure, or hearing-related causes. When those checks are normal and the sensation changes while chewing, opening the mouth, or clenching, jaw muscle and jaw joint load may be part of the pattern.
Evidence and limits for this question
What this question checks
This page uses the question "My hearing test was normal, but my ear still feels full. Could TMJ 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, severe dizziness, ear discharge, fever, or rapidly worsening symptoms should be evaluated by ENT first.
