The Waterlase technology utilizes a unique blend of laser energy and water to perform dental procedures without the use of a drill. As the Waterlase laser generally requires no anesthesia, you do not have the accompanying numbness. It’s also popular because more cavities can be treated in one visit, which is very convenient for patients. The Waterlase laser can also be used for: root canal procedures, bone procedures such as crown lengthening, reshaping “gummy” smiles, and general soft tissue procedures.
