In general, effective plaque removal and gum disease prevention are necessary to maintain healthy teeth. A plaque is a sticky, transparent film that sticks to the surface of a tooth and is also called a plaque. Plaques are made up of many germs (bacteria) living in the mouth clinging to certain components in saliva, and also in teeth, prostheses, orthodontic appliances, dentures and their surroundings. Germs in the plaque not only damage the gums by creating toxins and free oxygen, but they also damage the teeth and surrounding tissues. When the teeth and gums are damaged, they become swollen, bloody, and bad breath. In particular, plaque accumulation in the periodontal pouch caused by the gap between the teeth and gums damages the bone supporting the tooth, and in the worst case, the tooth is lost.
