Short Answer
It can be possible when one jaw joint or one side of the chewing muscles carries more load.
How to think about it
The jaw moves on both sides, but load can build more on one side through chewing side, sleep posture, clenching, tooth contact, or one-sided muscle tension.
Evidence and limits for this question
What this question checks
This page uses the question "Only one ear feels full. Could a dental or jaw issue 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
One-sided hearing loss or suspected ear inflammation should be evaluated by ENT first.
