Periodontitis is a serious infection of the gums. It's caused by bacteria that have been allowed to accumulate on your teeth and gums. As periodontitis progresses, your bones and teeth can be damaged. However, if periodontitis is treated early and proper oral hygiene is maintained, the damage can be stopped.

Where can periodontitis be found?

Periodontal diseases are mainly the result of infections and inflammation of the gums and bone that surround and support the teeth. In its early stage, called gingivitis, the gums can become swollen and red, and they may bleed.

Where does periodontitis start?

Red, swollen gums: That's one of the first signs your gums need attention. “Gum diseases typically start with inflammation along the gum line,” says Erik Sahl, DDS, assistant professor of periodontics at Loma Linda University. They may also feel tender or painful and bleed easily when you floss or brush.
