PROBLEM TO BE SOLVED: To provide a dental appliance which improves efficiency of removing impurity such as tooth coating, scale inside the peridontal pocket. SOLUTION: The appliance is provided with an optical beam generator 2 for generating optical beams of single or a plurality of wavelengths, a tank 3 filled with an oxidizing agent, and a nozzle 6 internally provided with a light guide path for guiding the optical beams of single or a plurality of wavelengths generated by the optical beam generator 2 and an oxidizing agent guide path for guiding the oxidizing agent supplied from the tank 3. While the tip of the nozzle 6 is inserted between a tooth T and the gum G, the optical beams are emitted from the tip of the nozzle 6 and simultaneously the oxidizing agent is jetted to generate active oxygen by the light action of the optical beams to the oxidizing agent. Thereby, the scale (including the tooth coating) P as the impurity existing on the surface of the tooth T and between the tooth T and the gum G (peridontal pocket) is removed.
