Periodontal (gum) Therapy: Periodontal disease, also known as gum disease, is a potentially serious condition in which the gum tissue surrounding the teeth becomes infected and inflamed. Over time, this infection can erode the bone around the teeth, loosening them and eventually causing tooth loss. Once, gum disease required painful surgery, but today periodontal gum therapy is convenient laser dentistry treatment. While conventional gum treatment often requires repeated procedures to be effective, laser gum therapy is less painful, less invasive, and more effective in a single treatment.
