Dental lasers work on the same principle as lasers used for medical procedures. Using lasers, we remove problematic tissue in the oral cavity by focusing a beam of light directly at the area to be treated. The beam can be focused so precisely that surrounding tissue is unaffected. Working with a dental laser, we can perform many procedures without discomfort and with little or no bleeding after treatment. Some procedures we commonly perform using dental lasers are gingevectomy (to remove excess gum tissue), frenectomy (to fix a tongue tie), and relief from cold and canker sores.
