Dental laser

[6][8] The soft tissue is cut, on contact, by the hot charred glass tip and not by the laser beam itself.

This is used for variety of oral surgery procedures such as gingivectomy, frenectomy, treatment of pericoronitis, and exposure of superficially impacted teeth.

[6][8] Similarly Nd:YAG lasers are used for soft tissue surgeries in the oral cavity, such as gingivectomy, periodontal sulcular debridement, LANAP, frenectomy, biopsy, and coagulation of graft donor sites.

The Nd:YAG laser wavelength are partially absorbed by pigment in the tissue such as hemoglobin and melanin.

[14] The 9,300 nm laser ablates hard tissue in excess of 5,000 °C, which often results in extremely bright thermal radiation.

[15] In September 2016, the Cochrane collaboration published a systematic review of the current evidence comparing the use of lasers for caries removal, in both deciduous and adult teeth, with the standard dental drill.

Overall, the quality of the evidence available was found to be low, and the authors were unable to recommend one method of caries removal over the other.
