The traditional treatment for bruxism has been an occlusal guard (night guard) – a plastic appliance worn in the mouth similar to an athletic mouth protector, which covers the teeth of one arch, which allows the patient to bite on plastic so there is no tooth-to-tooth contact while biting.
It is key that the molars and canines do not touch anything in order to sufficiently reduce jaw clenching. While both devices protect the teeth from wear, the NTI will also prevent TMD and headache pain by preventing canine and molar contact.
