Bruxism

Bruxism is the grinding of teeth during sleep. This typically occurs while in Stage 2, or N2, sleep. You can see the EMG signal increases (chin activity) and the tension throughout the EEG channels from muscle tension while grinding teeth.  Bruxism_sleep_study_teeth_grinding_parasomnia_example

Dentists have found that 10-20% of patients have evidence of bruxism. Of those, about 10% have enough damage to their teeth to require treatment.

Bruxism can be caused by anatomical problems that may be corrected. Lesions in the central nervous system may be possible, though rare.

Realistically the best treatment is prevention of further damage to the teeth by wearing a bite guard. A dental examination would be needed for a custom made bite guard.

If you have a bed partner and you have bruxism, it is very likly that they have heard you grinding your teeth.  The sound is AWFUL!
