Why your gums
bleed

Many people think it's normal for gums to bleed when brushing. It isn't — it's the first sign that something is wrong.

Usually it's gingivitis

The most common cause is gingivitis: an inflammation caused by dental plaque and tartar built up at the gum line. The good news is that, caught early, it clears up completely.

What to do at home

Don't stop brushing out of fear — quite the opposite. Brush gently but thoroughly, and floss daily. Within a few days, a healthy gum stops bleeding.

A healthy gum doesn't bleed. If it does, your body is sending you a signal.

When to come in

If the bleeding lasts more than a week or visible tartar appears, you need professional scaling. Ignored, gingivitis can progress to periodontitis, which affects the bone.
