Grinding of teeth usually occurs at night when you are sleeping. However, diagnosis of this destructive function is not seen until significant wear and tear has occurred on the teeth. If you wake up in the morning with a sore jaw or headache, you may be a nighttime grinder. Dr. Leyba will check your bite and determine if intervention is needed in order to prevent further wear or teeth fractures. A simple bruxism (grinding) appliance can help prevent this type of destruction.
