Abstract
A method of ablating non-metallic dental material from a tooth comprises the steps of generating radiation pulses having a predetermined wavelength, energy level, pulse repetition rate, and duration, and applying the radiation pulses to the non-metallic dental material in a tooth, whereby the non-metallic dental material is ablated from the tooth. The radiation may be generated by a frequency tripled Nd:YAG, an Er:YAG laser or an Er:YsGG laser and may have a wavelength of about 355 nanometers, 2.94 micrometers, and 2.79 micrometers respectively, for example.
