Gum disease describes swelling, sorness or infection of the gum tissue.
There are 2 main forms of gum disease:
Gingivitis
Gingivitis is the mildest form of gum disease. Your gums will be red and swollen and may also bleed easily when you brush your teeth. There is usually little or no pain.
Periodontitis
Untreated gingivitis can lead tp periodontitis. As plaque spreads and grows below the gum line the tissues and bone that support your teeth are broken down and destroyed. Your gums may become separated from your teeth to form pockets, which become infected. Eventually teeth may become loose and have to be removed.
