Laser dentistry was developed in the year 1994 for treating a number of dental problems. Though FDA has approved the use of laser in dentistry no laser system has got acceptance from the American dental association seal. This seal guarantees that products and devices meet ADA standards of safety and efficiency.
ADA is cautious about the use of laser dentistry in oral healthcare. This is because the lasers used are very much different from those which are used in phototherapy for getting relief from pain, inflammation, and headaches.
Still, various dentists are using laser technology in treating the following ailments:
- Gum disease: Lasers dentistry can help in reshaping gums and in removing bacteria via root canal treatment.
- Tooth decay: Lasers help in getting rid of decay from the tooth. Also, it prepares the surrounding enamel for receipt of the filling. Lasers also help in hardening filling.
- Biopsy or removal of lesion: Laser dentistry has proven quite effective in removing small tissue pieces known as biopsy so that they can be used for examining cancer. Lasers also help in removing lesions in the mouth and also to get relief from canker sores.
- Teeth whitening: Laser dentistry wonderfully works in the teeth whitening process. In this procedure, the peroxide bleaching solution can be applied on the surface of the tooth and then the whitening process is activated and speeded up using laser energy.
