Why are my gums bleeding?
Gums that bleed when you brush or floss are common, but they aren't normal. Most often it's an early sign of gum disease that can still be reversed. Here's what else can cause it, and what to do.
Medically reviewed by Dr. Rodolfo Rodriguez, DMD · Updated
Common causes
- Gingivitis. Plaque along the gumline inflames the gums. This is the most common cause, and it is reversible.
- Brushing too hard, or with a hard-bristled brush.
- Starting to floss. Gums often bleed for the first week or two, then settle as they get healthier.
- Pregnancy. Hormone changes make the gums more sensitive to plaque.
- Medications that thin the blood.
- Something rubbing, such as a rough filling edge or a denture that no longer fits.
Smoking can hide bleeding, so gums that never bleed in a smoker are not proof they are healthy.
What to do at home
- Brush twice a day for two minutes with a soft brush, angled toward the gumline
- Clean between your teeth every day with floss or small brushes — and keep going even if they bleed at first
- Keep your regular cleanings
If the bleeding has not improved after two weeks of careful cleaning, book a visit.
When to see us sooner
- Gums that bleed on their own, without brushing
- Swelling, pain or pus around a tooth
- Teeth that feel loose, or gums that have pulled back
- Bad breath that does not go away
If you also bruise easily or have frequent nosebleeds, see your physician as well.
What we do
Dr. Rodriguez measures the gums around each tooth and checks the bone on X-rays. Gingivitis usually clears with a professional cleaning and better habits at home; deeper problems need a deep cleaning. See gum disease treatment.
