We can create a custom-fitted plastic mouthguard to protect your teeth, gums, lips and cheeks from sports-related injuries. Athletic mouthguards can even help prevent severe injuries to the face, jaw, and head. Dr. Harmeyer can help you protect your teeth from the effects of grinding with a custom-made nightguard. This plastic guard is worn at night while you sleep, and covers and preserves the teeth you have been grinding. Nightguards have also been shown to reduce or eliminate jaw pain and headaches that often are associated with grinding.
