Dental Laser Treatment

Lasers have been used in dentistry since 1994 to treat a number of dental problems. But, despite FDA approval, no laser system has received the American Dental Association’s (ADA) Seal of Acceptance. That seal assures dentists that the product or device meets ADA standards of safety and efficacy, among other things. The ADA, however, states that it is cautiously optimistic about the role of laser technology in the field of dentistry. These lasers are different from the cold lasers used in phototherapy for the relief of headaches, pain, and inflammation.

Still, some dentists are using lasers to treat:

Tooth decay. Lasers are used to remove decay within a tooth and prepare the surrounding enamel for receipt of the filling. Lasers are also used to “cure” or harden a filling.
Gum disease. Lasers are used to reshape gums and remove bacteria during root canal procedures.
Biopsy or lesion removal. Lasers can be used to remove a small piece of tissue (called a biopsy) so that it can be examined for cancer. Laser are also used to remove lesions in the mouth; and relieve the pain of canker sores.
Teeth whitening. Lasers are used to speed up the in-office teeth whitening procedures. A peroxide bleaching solution, applied to the tooth surface, is “activated” by laser energy, which speeds up of the whitening process.

How Do Lasers Work in Dentistry?

All lasers work by delivering energy in the form of light. When used for surgical and dental procedures, the laser acts as a cutting instrument or a vaporizer of tissue that it comes in contact with. When used for “curing” a filling, the laser helps to strengthen the bond between the filling and the tooth. When used in teeth whitening procedures, the laser acts as a heat source and enhances the effect of tooth beaching agents.
What Are the Pros and Cons of Using a Laser in Dentistry?

Compared to the traditional dental drill, lasers:

May cause less pain in some instances, therefore, reducing the need for anesthesia
May reduce anxiety in patients uncomfortable with the use of the dental drill
Minimize bleeding and swelling during soft tissue treatments
May preserve more healthy tooth during cavity removal
