In laser gum treatments performed by applying double wavelength “WPT technique”, all foreign materials and tissues around the tooth are cleaned with Er:YAG laser without invasive surgical procedures. Thus, the natural state of tissue biology is provided, and the blood that fills the cavity of the bone that melts angularly around the tooth is stimulated with Nd:YAG laser to clot, and the body is enabled to form bone and other healthy tissues by transforming the clot. Thus, there is no need for advanced surgical procedures and foreign materials such as bone dust.
