With high heat and tremendous pressure we form the material to an exact model of your mouth and then finish by hand a night guard that will fit you perfectly.

Bruxism is defined by the American Dental Association as: The parafunctional (other then normal function) grinding of the teeth. More clearly defined by the Mayo Clinc, Bruxism (BRUK-siz-um) is a condition in which you grind, gnaw or clench your teeth. If you have bruxism, you may unconsciously clench your teeth together during the day (awake Bruxism), or clench or grind them at night (sleep bruxism).Sleep bruxism is considered a sleep-related movement disorder. People who clench or grind their teeth (brux) during sleep are more likely to have other sleep disorders, such as snoring and pauses in breathing (sleep apnea).
