tonguethrusting

Tongue thrusting, also known as reverse swallow, is a type of swallowing pattern where the tongue is pushed forward between the teeth instead of resting against the roof of the mouth. This pattern typically begins in infancy as a normal reflex for swallowing. However, for some individuals, this reflex persists into adulthood.

The reasons for persistent tongue thrusting can vary. It may be related to factors such as prolonged pacifier or bottle use, thumb sucking, enlarged tonsils or adenoids, or even certain oral habits. In some cases, it can be a learned behavior.

Tongue thrusting can have several consequences. It may contribute to dental issues, such as an open bite where the front teeth do not meet, or misaligned teeth. Speech patterns can also be affected, potentially leading to difficulty with sounds that require the tongue to be in specific positions, like "s" or "z". Some individuals may also experience difficulties with chewing and may develop altered facial muscle patterns.

Diagnosis of tongue thrusting is usually made by a dentist, orthodontist, or speech-language pathologist. Treatment often involves a combination of approaches. Behavioral therapy, such as speech therapy, is commonly used to retrain the tongue's resting position and swallowing pattern. Orthodontic intervention may be necessary to address dental alignment issues that have resulted from tongue thrusting. Early intervention is often recommended to prevent or correct potential problems.
