Tongue thrust, also known as reverse swallow or deviate swallow, is a condition in which the tongue is pressed up against the teeth or between them while gulping. In many cases, this condition leads to the movement of the tongue incorrectly to the sides, instead of forward to the teeth. This improper positioning of the tongue can occur even as the tongue is at rest, and in this case, it will lie too far forward.
