Outside the scientific setting of a sleep laboratory, diagnosis of sleep bruxism mainly relies on examination for clinical evidence – e.g. indicated by the tips of the teeth appearing flat – and on standardized questionnaires. To date there is a lack of a user-friendly and validated devices for standardized, quantitative diagnosis available. As a result, bruxers are often diagnosed at late stage, when severe consequences of teeth grinding, such as abraded teeth, facial pain, headache and damage to the temporomandibular joints are apparent.
