Answer 2

Your gums are very important to your oral health. The gums are made of firm, pink tissue that covers your jawbone. This tissue is thick, fibrous, and full of blood vessels.

If your gums become swollen, they may protrude or bulge out. Swelling in your gums usually begins where the gum meets the tooth. Your gums may become so swollen, however, that they begin to hide parts of your teeth. Swollen gums appear red instead of their normal pink color.

Swollen gums, also called gingival swelling, are often irritated, sensitive, or painful. You may also notice that your gums bleed more easily when brushing or flossing your teeth.
