The more severe form of gum disease is called periodontitis. When you reach this stage, your gums begin to pull away from your teeth. Pockets form between your teeth and gums. These fill with germs and pus, and deepen. When this happens, you may need gum surgery to save your teeth. If nothing is done, the infection goes on to destroy the bone around your teeth. The teeth may start to move or get loose. Your teeth may fall out or need to be pulled.
