**5.6 Microabrasion**

The esthetic appearance of WSL, which has been going on for a long time, can be improved with the microabrasion method. It has been suggested to use the microabrasion technique in the treatment of white spot lesions that occur during dental treatment [61]. Researchers stated that when a mixture of 18% hydrochloric acid, pumice, and glycerin was applied to the tooth surface for 3–5 minutes with an electric toothbrush, mild lesions disappeared completely, while severe lesions reached a satisfactory color. They also stated that the brown-yellow discoloration on the tooth surface disappeared, and smooth enamel surfaces were obtained.
