Dental lasers are either an indispensable tool in a dentist‘s toolkit or an emerging-but-unproven technology. It depends on whom you ask.
They came into use in general dentistry about 15-20 years ago but even now are used only by about 6% to 8% of dentists nationwide. The two main categories are soft-tissue lasers,used mostly for gum contouring and minor surgical procedures,and hard-tissue lasers, used to treat small- to moderate-size cavities.
