Tongue positioner products are oral appliances designed to help maintain correct tongue posture, supporting improved breathing, swallowing, and dental alignment. In New Jersey, they are commonly used in orthodontic care and myofunctional therapy for patients with habits like tongue thrusting or mouth breathing. According to the American Association of Orthodontists, proper tongue positioning can contribute to long-term orthodontic stability and facial development. However, effectiveness depends on correct diagnosis and supervision. A licensed orthodontist or orofacial myofunctional therapist should evaluate whether a tongue positioner is appropriate and guide its safe, individualized use.
