Abstract
An optical toothbrush used for medical treatment comprises a plurality of narrow fibers connected to a light generating device and extending through a brush base, wherein the fibers are bent to form an L-shape and project outwardly from the base to form a brush. Light emitted from the light generating device is guided into each fiber at its base and projected through the brush tips to provide oral hygiene.
