Since bruxism is not life-threatening,[5] and there is little evidence of the efficacy of any treatment,[6] it has been recommended that only conservative treatment which is reversible and that carries low risk of morbidity should be used. Teeth grinding (bruxism) is a serious condition that affects 8-16% of adults and 14-20% of children.. Overall between 1966 and 2007, most of the research published was focused on occlusal adjustments and oral splints. [16] Others suggest that there is no strong association between TMD and bruxism.
