The term “laser” originated as an acronym for “Light Amplification by Stimulated Emission of Radiation”. Which is basically, super focused light energy. For over 50 yrs, lasers were used in medical surgery and in the past 25 yrs, they have applied that advanced tech to dentistry.
I use the “Waterlase iPlus” dental laser in my practice. It allows me to practice at the highest level of conservative dentistry. The more you can conserve the better the outcomes/less pain my patients will have. For example, I can do fillings without requiring shots, contour gums without a scalpel, and treat gum diseases without painful surgery. Although these are the most common ways I use the laser, it has many more phenomenal applications.
