A laser is a tiny beam of very concentrated light . This beam of light brings energy into your mouth through a tiny fiber, to help remove areas of infection and remove gum disease around the teeth with great precision and accuracy.
The laser beam sterilizes the affected area and seals off blood vessels, which minimizes the chance of infection or bleeding. Patients are also much more comfortable during and after treatment with laser therapy. The need for local anesthetic is reduced but it is usually used to make sure that you feel absolutely nothing during the treatment.
