subject: Latest in Dental Technology [print this page] Laser dentistry allows dentists to treat diseased oral tissue without damaging the surrounding, healthy tissue. This procedure involves a precise, specialized beam of light that destroys decay. One of the unique advantages of laser dentistry is that it considerably reduces bleeding, swelling and discomfort, while eliminating the need for an anesthetic. Today, lasers are being used to treat gum disease and for lengthening crowns to treat cold sores and controlling orthodontic tissue. Laser treatment is used for both hard and soft tissue. Laser MD for hard tissue minimizes heat and vibration associated with dental drilling. Diode lasers are mainly used for soft tissue treatment. They can be used for non-surgical treatment of gum disease, removal of plaque and infected tissues and helps in healing.
