The Chairside Instructor 14 Stages of Gum Disease Gum Disease Normal, Healthy Gums Your teeth are held in place by gums, bone and connective tissues. Your gums tightly hug your teeth and there is little or no buildup of plaque and tartar on them. Gingivitis The bacteria in plaque make your gums red, tender, and swollen. Your gums might bleed at this stage. You also can have gingivitis and not have any signs of it. Periodontitis In time, your body responds to the harmful toxins that the bacteria produce by breaking down the gum tissues and bone around your teeth. Advanced Periodontitis Your teeth may become loose, fall out or need to be removed by your dentist. Loose or missing teeth can create problems, like making it hard for you to eat the foods you like.
