Abstract: A toothbrush with variable adjustment of operative bristle length, characterized by inclusion of an attenuate flexible pivotal appendage secured to the brush toward the handle end, extending over a depression midway along the length of the brush body. The appendage includes an aperture or a grid of holes encompassing the bristles and is positioned at the base of the bristles when the appendage is at rest, or in a retracted position. Digital pressure applied on the appendage above the depression, causes a lever action whereby the device moves perpendicularly to the bristles. A tether is provided to prevent the travel of the appendage beyond the bristle ends.
