Because of the forces exerted on the teeth and Temporomandibular Joint, teeth grinding (bruxism) can cause extensive damage to your teeth and jaws, cause Temporomandibular disorders and impact your overall bite. Most patients are not aware of teeth grinding because they do it during sleep. Many factors can cause bruxism, including stress or anxiety. Problems with jaw alignment and the way teeth come together are often other factors. Using a custom-made night guard can not only protect the teeth, but it can also relieve pressure on the TMJ as well.
