From the wikipedia article\u00a0https:\/\/en.wikipedia.org\/wiki\/Tongue_thrust<\/a><\/p>\n

Tongue thrust<\/b>\u00a0(also called\u00a0reverse swallow<\/b>\u00a0or\u00a0immature swallow<\/b>) is the common name of\u00a0orofacial muscular imbalance<\/b>, a human behavioral pattern in which the\u00a0tongue<\/a>\u00a0protrudes through the anterior\u00a0incisors<\/a>\u00a0during\u00a0swallowing<\/a>,\u00a0speech<\/a>, and while the tongue is at rest. Nearly all infants exhibit a swallowing pattern involving tongue protrusion, but by six months of age most lose this reflex allowing for the ingestion of solid foods.[1]<\/a><\/sup><\/p>\n

Since 1958, the term “tongue thrust” has been described and discussed in speech and dental publications by many writers.[citation needed<\/span><\/a><\/i>]<\/sup>\u00a0Many school-age children have tongue thrust. For example, according to recent literature, as many as 67\u201395 percent of children 5\u20138 years old exhibit tongue thrust, which may be associated with or contributing to an\u00a0orthodontic<\/a>\u00a0or speech problem. Up to the age of four, there is a possibility that the child will outgrow tongue thrust. However, if the tongue thrust swallowing pattern is retained beyond that age, it may be strengthened.[citation needed<\/span><\/a><\/i>]<\/sup><\/p>\n\n\n\n\n\n\n\n\n\n
Types<\/caption>\n
Name<\/th>\nDefinition<\/th>\n<\/tr>\n
Anterior open bite<\/td>\nThe most common type of tongue thrust. In this case, the front lips do not close and the child often has his mouth open with the tongue protruding beyond the lips.<\/td>\n<\/tr>\n
Anterior thrust<\/td>\nUpper incisors are extremely protruded and the lower incisors are pulled in by the lower lip. This type of thrust is most generally accompanied by a strong\u00a0mentalis<\/a>.<\/td>\n<\/tr>\n
Unilateral thrust<\/td>\nThe bite is characteristically open on either side.<\/td>\n<\/tr>\n
Bilateral thrust<\/td>\nThe anterior bite is closed, but the posterior teeth from the first\u00a0bicuspid<\/a>\u00a0to the back\u00a0molars<\/a>\u00a0may be open on both sides. This is the most difficult thrust to correct.<\/td>\n<\/tr>\n
Bilateral anterior open bite<\/td>\nThe only teeth that touch are the molars, with the bite completely open on both sides including the anterior teeth. A large tongue is also noted.<\/td>\n<\/tr>\n
Bimaxillary Thrust (closed bite thrust)<\/td>\nTypically shows a double protrusion meaning that both the upper and lower teeth are flared out and spread apart<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
