Abstract: A bruxnostic device includes a plastic channel configured to be received over a plurality of teeth of an individual. The bruxnostic device further comprises a layer of pressure-indicating material enclosed within the plastic channel in a position to be disposed between maxillary teeth and mandibular teeth of the individual when the plastic channel is received over the plurality of teeth. The pressure-indicating layer produces a color indication in response to pressure between the maxillary teeth and the mandibular teeth.
