Abstract

A toothbrush includes a handle and a brush head removably connected to the handle. There is a spring for biasing the brush head away from the handle. A latch normally secures the brush head on the handle. There is a release mechanism for selectively releasing the latch, whereby the spring ejects the brush head away from the handle.
