Lip and tongue ties (also known as tethered oral tissues or TOTs) are more than just breastfeeding concerns. If left untreated, they can have a lasting impact on the development of the mouth, jaw, and airway.

1. Effects on Teeth

When the tongue is restricted and cannot rest against the palate, the upper jaw may not develop properly. This often results in a high, narrow palate and crowded teeth, increasing the need for orthodontic work later in life.

2. TMJ and Muscle Strain

A restricted tongue can cause compensatory movements in the jaw and surrounding muscles, leading to strain, imbalance, and temporomandibular joint (TMJ) dysfunction. Symptoms can include headaches, jaw pain, clenching, and even neck discomfort.

3. Airway and Breathing

Tongue posture plays a critical role in airway development. If the tongue is tethered and sits low in the mouth, it can contribute to mouth breathing and narrowed airways—raising the risk for sleep-disordered breathing or obstructive sleep apnea.

4. Why Early Intervention Matters

Early diagnosis and treatment—often through a frenectomy combined with myofunctional therapy—can help correct oral posture, relieve strain on the TMJ, and support healthier breathing patterns.
