1. A method of cutting dental tissue comprising:
providing a handpiece including a grip region, a treatment tip arranged at a distal end of the handpiece, and a light conduction device disposed in the handpiece and configured to provide laser light to cut the dental tissue;
configuring the handpiece to operate in a first mode of operation wherein the laser light is configured to have a wavelength and optical power output combination of 445±20 nm and 2 W to 5 W;
directing the laser light in a light path from a light source to the dental tissue, the directing starts from the light source, through an outlet point of the treatment tip and onto the dental tissue to non-contactly cut the dental tissue, wherein the dental tissue is processed substantially by energy generated in the dental tissue by absorption of the laser energy and not thermal transmission of energy from the treatment tip to the dental tissue; and
configuring the handpiece to operate in a second mode of operation wherein the laser light is configured to have a wavelength and optical power output combination of 410±10 nm and 1 W to 2 W, wherein the handpiece is guided over the dental tissue in a contact manner to cut said dental tissue using the treatment tip.
