Tongue thrust, also known as a reverse swallow or infantile swallow, occurs when the tongue pushes against the teeth during swallowing. This can lead to dental and orthodontic problems, such as malocclusions and an open bite. There are several synonyms for the term tongue thrust, including tongue thrusting, anterior tongue posture, and lingual interposition. Some professionals may also use the term orofacial myofunctional disorder to describe these issues. Treatment for tongue thrust often involves working with a speech-language pathologist or myofunctional therapist to address any underlying muscle issues and improve oral motor skills through exercises and techniques.
