Abstract
A teeth exerciser adapted to be inserted in the mouth so that biting or chopping thereon will exercise the teeth. The teeth exerciser has a generally U-shaped configuration and is formed from a yieldable resilient material such that the bite surface or portion of the device will provide a generally uniform reaction pressure on all teeth being exercised. Upstanding positioning flanges extend from portions of the inner and outer edges of the bite surface.
