Tests and diagnosis

By Mayo Clinic Staff

During regular dental exams, your dentist likely will check for signs of bruxism. If you have any signs, your dentist will look for changes in your teeth and mouth over the next several visits to see if the process is progressive and to determine whether you need treatment.

If your dentist suspects that you have bruxism, he or she will try to determine its cause by asking questions about your general dental health, medications, daily routines and sleep habits.

To evaluate the extent of bruxism, your dentist may check for:

  • Tenderness in your jaw muscles
  • Obvious dental abnormalities, such as broken or missing teeth or poor tooth alignment
  • Damage to your teeth, the underlying bone and the inside of your cheeks, usually with the help of X-rays

A dental exam may detect other disorders that can cause similar jaw or ear pain, such as temporomandibular joint (TMJ) disorders, other dental problems or an ear infection.

If your dentist suspects a significant psychological component to your teeth grinding or a sleep-related disorder, you may be referred to a therapist, counselor or sleep specialist. A sleep specialist may conduct more tests, such as assessment for sleep apnea, video monitoring and measuring how often your jaw muscles tighten while you sleep.
