Deprogrammers are short-term oral splints used in dentistry to deprogram muscle memory in your jaw muscles. The term dental deprogrammer originated in dental concepts focused on neuromuscular reprogramming and how the masticatory muscles function when you chew, swallow, talk, yawn and make facial expressions. A deprogrammer can release habitual, subconscious tension in the jaw muscles. In this sense, anterior deprogrammers are more about muscles and less about your teeth.
