Night Guards (Bruxism)

Night guards are removable acrylic appliances worn on the top or bottom teeth to protect from clenching or grinding (bruxism).

Grinding or clenching your teeth may result in many adverse effects, including worn or broken teeth, muscle tension headaches, and temporomandibular joint (TMJ) problems.  If you show evidence of grinding your dentist may recommend that you wear a night guard while you sleep.  A night guard is a removable acrylic appliance that protects your teeth from the adverse forces of grinding or clenching.
