Treatment of Sleep-Related Bruxism (SB)

There is no cure for Sleep-Related Bruxism (SB). Dental guards or oral splints are the first line of treatment for SB, in order to prevent damage to teeth and other orofacial structures, relieve temporomandibular joint (TMJ) pain, and eliminate noises that disturb bed partners and/or family members.80

Pharmacological therapy has been met with limited success, although studies suggest that the anti-seizure medication clonazepam is effective at improving patients’ sleep efficiency, maintenance, latency, awakenings, and nocturnal wake time.81 82
