<p>The ultraviolet light toothbrush has a replaceable brush insert, and an ultraviolet diode (1) which is used for illuminating the oral cavity to check the in-depth dental care. The ultraviolet diode is integrated at the front end of the toothbrush. A substance, such as titanium dioxide reflecting sufficient ultraviolet-radiation through tooth cream is massaged on the teeth enamel after two minutes of thorough cleaning of teeth. A waterproof battery compartment is present in the handle of the toothbrush. The tooth cream dampens the tooth enamel with an ultraviolet-reflecting substance after intensive tooth care, such that an optimum of the illumination force is shown on the teeth under the influence of ultraviolet-light while examining the ultraviolet-illumination tooth brush.</p> |
