Although the causes of tooth-grinding aren't fully known, stress may be a contributing factor. Other factors can be problems with sleep, crooked or missing teeth, or a malocclusion.
People who grind or clench their teeth often wake with facial and teeth pain. Grinding teeth can cause damage such as cracks, factures and even abrasion to the dentinal tooth structure (the soft area underneath the tooth's enamel). Ask Dr. Budz about making you a night guard which may be the solution that puts an end to your pain and dental damage.
