Bleeding gums are a sign of gingivitis, or inflammation of your gums. It's a common and mild form of gum disease, and it's caused by a buildup of plaque at your gumline.
If you have gingivitis, your gums may be irritated, red, and swollen. They may bleed when you brush your teeth.
You can get rid of this problem by taking good care of your teeth. Brush your teeth twice a day, floss every day, rinse daily with an antibacterial mouthwash, and see your dentist regularly.
