Positive behaviour change is used in Orofacial Myology to remove habits, such as thumb sucking, reverse swallow pattern (tongue thrust), nail/pen biting, and/or mouth breathing that can lead to unfavored growth patterns.

Myofunctional therapy is a retraining procedure that improves sleep quality and overall health by retraining a person's ability to position their tongue correctly and breathe properly. This procedure is often used in combination with frenectomy (tongue-tie release), habit cessation, and orthodontics. The improvement of tongue posture, nasal breathing, jaw function, and natural facial development is aided by therapy.
