Dr. Tatevossian generally uses a local anesthesia prior to performing laser gum contouring. Different types of dental lasers have been created to treat different conditions. Each laser uses a different wavelength of light, which predicates its best use. The most common types of dental lasers are carbon dioxide lasers and diode lasers, which are usually employed to treat soft tissue problems. Dr. Tatevossian will decide which type of laser is best to use after conducting X-rays and a thorough examination.
