Is bruxism related to sleep disorders?

Bruxism is often related to sleep disorders, particularly obstructive sleep apnea (OSA). People with sleep apnea experience repeated interruptions in their breathing during sleep, which can cause them to clench or grind their teeth as a reflexive response. Bruxism can also be associated with other sleep disorders, such as insomnia or parasomnias (unusual behaviors during sleep). Addressing the underlying sleep disorder, such as through the use of a continuous positive airway pressure (CPAP) machine for sleep apnea, can help reduce the occurrence of bruxism.
