Abstract

The disclosure relates to a device for preventing tooth decay by use of laser beams and to a method of preventing tooth decay by use of such a device. According to the invention, high-speed repetition pulses projected from Q-switched continuous excitation Nd:YAG laser is irradiated upon teeth through a glass beam guide, whereby treatment of the teeth is reduced in time, is safe, effective and is readily useable for use by general practice.
