A method to enhance migraine prevention and treatment of temporomandibular disorders with use of an intraoral discluder device includes providing the intraoral discluder device. The intraoral discluder device has a trough with a front wall and a rear wall designed to accommodate at least one maxillary incisor or mandibular incisor of the user, and a protrusion coupled to the trough. The method further includes maneuvering the intraoral discluder device in the user to accommodate the at least one maxillary incisor to permit the protrusion to contact at least one mandibular incisor of the lower jaw during a bite of the user, determining the spacing between the maxillary molars and mandibular molars, and ensuring the spacing between the maxillary molars and mandibular molars is no greater than approximately 2 millimeters during the bite.
