A: Many people who notice chipped or cracked teeth, but who don’t remember when the injury occurred, damaged their teeth while they were sleeping. Grinding or clenching your teeth during the night will cause your teeth to chip, crack and even break. To keep you from seriously damaging your teeth, we recommend a dental appliance called a nightguard. A custom fitted nightguard protects your teeth from grinding and clenching in your sleep. Dr. Hamman takes great care in making sure you have a proper fit in order to prevent pain in your jaw joint. Ask us about having a nightguard custom created especially for you.
