Gingivitis
If your gums are swollen, tender and bleed easily when you brush your teeth, you’re not alone — nearly 80 percent of American adults have some form of gum (periodontal) disease. One of the most common of these is gingivitis, which develops when bacteria multiply and build up between your teeth and gums, leading to irritation, inflammation and bleeding. If not treated, gingivitis can progress to more-serious gum diseases, such as periodontitis, and eventually to the destruction of bone and to tooth loss.
