Periodontal disease is an infection of the underlying supporting structures of the teeth. These are gums and bone infections caused by the bacteria (germs) in your mouth. The main cause of these diseases is a bacterial plaque, a sticky, colorless film that constantly forms on your teeth. If plaque is not removed on a daily basis it can build up on the tooth surface and turn into a hard substance called calculus. periodontal disease is painless and can cause bad breath and swollen bleeding gums and eventually tooth loss. We use the laser to treat periodontal disease which is less invasive and more comfortable than gum surgery (cutting gums). Patients report no post-operative pain or discomfort.
