Abstract
Tongue thrust, or reverse swallow, is evidenced by the incorrect placement of the tongue between the upper and lower teeth in swallowing or at rest. 1 Most dentists and speech pathologists associate the term "tongue thrust" with concomitant speech problems and malocclusions that may require orthodontic appliances. From her own files, the author cites case histories of adults who developed serious oral conditions as a result of tongue thrust conditions.
