Make sure you don't have any dental problems. See a dentist and make sure you don't have temporo-mandibular joint disease, or any kind of dental or jaw problem that could be causing your tinnitus. In some cases, taking care of dental issues could alleviate any tinnitus you might be experiencing.
A helpful method for dealing with tinnitus is to lower the stress levels in your life. When people become tense or anxious, they have a tendency to focus more on their tinnitus. Some techniques which are beneficial in stress reductions are biofeedback, meditation, and exercise. Getting enough sleep each night can also aid in stress reduction.
