ABSTRACT:
A lip and cheek retracting device formed from a rigid sheet of autoclavable material. A first pair of opposing prongs with a first space formed therebetween extends in the opposite direction of a second pair of opposing prongs with a second spaced formed similarly therebetween. The first pair of prongs are shaped to fit around an adult's gum ridge, and the second pair of prongs are shaped to fit around a child's gum ridge. An indented curvature formed in each portion of the peripheral edge lying between one prong of the first pair of opposing prongs and one prong of the second pair of opposing prongs is used for manually holding the device in place during use.
