While there is no direct link between teeth grinding (bruxism) and tinnitus, the two conditions can be related.
Tinnitus is a condition in which you hear ringing, buzzing, or other sounds in your ears that are not caused by an external source.
In some cases, tinnitus can be caused by damage to the inner ear, which can be caused by loud noises or certain medications. Teeth grinding can cause a grinding or clicking noise, which can be loud enough to potentially cause damage to the inner ear.
Additionally, grinding your teeth can cause muscle tension and pain in the jaw, which can lead to headaches and earaches. These symptoms can be similar to those of tinnitus, so it is possible that teeth grinding may worsen tinnitus symptoms in some people. Teeth Grinding and Tinnitus
