ABSTRACT:
A nipple appliance having a base portion, a bulb portion having an integrated internal mechanical device that expands as the child sucks on the bulb, and a neck portion connecting the base portion and bulb portion. A sucking force by a child activates the mechanical device by compression of a front of the nipple to redirect force outward and upward by expansion of lateral walls of the bulb, thereby conveying pressure against the palate, alveolar ridge, and/or the teeth.
