CAVITIES filled without a shot or a drill – LASER Dentistry !

Cavities filled without a shot or a drill? Sci-fi or reality? Reality-much of the time! Dr. Nick is a laser dentist who uses several lasers in his practice. This video demonstrates the Lightwalker erbium yttrium aluminum garnet (ERYAG) laser which operates at the 2940 wavelength. This wavelength has an affinity for both WATER and HYDROXYAPATITE, both of which are contained within human teeth. Guess what dental decay has plenty of? WATER! So yes, this laser can and will erase decayed tooth structure very easily, often times without a shot or a drill, as this video demonstrates on a 24 year old patient who didn’t brush her teeth…well enough 😉
