In childhood, the mouth and face are still growing, and the way muscles rest and move helps shape that growth. Chronic mouth breathing and low tongue posture can influence how the jaw and palate develop, how teeth align, and how restful sleep is. Tongue thrust can work against orthodontic treatment, which is one reason orthodontists often recommend myofunctional therapy alongside braces. Addressing these patterns during childhood, while growth is still happening, gives new habits the best chance to support healthy development.
If your child has a tongue tie, muscle retraining matters too. A release procedure frees the tongue’s range of motion, but therapy is often what teaches the tongue to actually use it, before and after the procedure.
