Dental laser can be used in many areas such as soft and hard tissue surgery, wound healing, tooth whitening, root canal disinfection, gingival shaping and tooth sensitivity. In surgical treatments and gingival operations performed with dental laser, the healing time of tissues is shortened and there is no bleeding. Disinfection of hard-to-reach root canals can be easily achieved. With dental laser, which can also be used in the field of teeth whitening, the treatment time is much shorter and fast results can be obtained. Tooth sensitivity treatment can be done.
