*Train*Retain*Breathe Free* Spot Pal is a custom fit daytime and nighttime tongue-training appliance. It is designed to teach proper lingual resting posture, eliminate tongue thrusting, retain the teeth and extinguish noxious oral habits including thumb/finger sucking and nail-biting. Habituating proper lingual resting posture supports proper facial growth and the natural expansion of the maxilla, while eliminating the tongue pressure on the dentition which maximizes retention. Proper oral posture encourages correct nasal breathing, supports the reduction in TMJ/D symptoms, maximizes the airway for restful sleep, and improves articulation.
