A light emitting electric toothbrush and method therefore is disclosed which is intended for use by children, is comprised of a robust high-strength, plastic construction, and employs both light and vibration to assist in the development of suitable dental hygiene skills. In its most fundamental embodiment, the light emitting electric toothbrush comprises a construction including a handle having a bottom end and a top end and a toothbrush shaft mounted to the top end of the handle. The brush shaft is comprised of a plastic resin including a fluorescent colored light refractive additive for optimizing light transmission through the brush shaft. A high intensity light source is mounted within the top end of the handle for generating light and a domed-shaped optical lens is positioned over the high intensity light source for directing the generated light into the brush shaft. Finally, a switched electrical source is included for energizing the light source and the generated light therefrom creates a glowing illumination in the brush shaft for illuminating a dental cavity of a person during brushing of the teeth. In a preferred embodiment, the toothbrush also includes a vibrating motor mounted within the handle for causing the brush shaft to vibrate. The vibrating motor is also energized by the switched electrical source simultaneously with the light source.
