Dental laser brushing or cleaning device

A treatment device to treat teeth, gums and other oral areas comprising:

• a handle, a brushhead, a radiation source, and a power source for said radiation source;
• said brushhead further comprising a backing plate and a multiplicity of bristles;
• said radiation source being a diode laser
• a delivery means for said radiation;
• said delivery means for said radiation comprising an optical fiber optically connected to said radiation source;
• said optical fiber being terminated such that said optical fiber's longitudinal axis is substantially directed at an opening in said brushhead;
• said opening allowing passage of a liquid and radiation to oral areas to be cleaned;
• a tube providing passage for liquid under pressure;
• said optical fiber having a termination-tip which forms a substantially flat surface relative to said optical fiber's longitudinal axis;
• said tube having an open-end substantially near said termination-tip;
• said liquid coming through said open-end passing over said surface of said termination-tip;
• an angle formed between said surface of said termination tip and said optical fiber's longitudinal axis forming a substantially refractive surface for said radiation while liquid is passing over said surface and then to said opening thereby passing said radiation substantially through said opening;
• and
• said angle forming a substantially reflective surface for said radiation when said liquid is not passing over said surface, thereby passing said radiation substantially to said brushhead.
