Why Do My Gums Bleed When I Brush? When to See a Dentist

Bleeding when you brush can have several causes. Gum inflammation is one possibility, but brushing too hard, getting used to a new flossing routine, pregnancy-related changes, or some medicines may also play a part. If the bleeding keeps happening, arrange a dental exam rather than trying to diagnose the cause at home.

Common reasons gums bleed

One common cause is gingivitis, an early form of gum disease. It can make gums bleed easily and may also cause redness, swelling, tenderness, or bad breath. Plaque along the gumline can contribute to this inflammation, but bleeding alone cannot confirm what’s happening.

Other possibilities include brushing with too much pressure or recently starting to clean between your teeth. The American Dental Association (ADA) notes that gums may bleed when someone is getting used to a new flossing routine; this usually settles within about a week. Pregnancy and some medications can also affect the gums or bleeding. If you take a blood thinner, don’t stop or change it on your own; contact your physician if bleeding does not stop quickly.

What you can do at home

Use a soft-bristled toothbrush and gentle pressure instead of scrubbing. Brush twice a day and clean between your teeth daily. If you have just started flossing, mild bleeding at first may settle as your gums get used to the routine. If it continues beyond about a week, returns regularly, or worries you, ask a dentist for guidance.

When should you see a dentist?

Make an appointment if your gums bleed easily or repeatedly when you brush or floss, or if they are puffy, red, or tender. The ADA recommends talking with a dentist about bleeding gums. An exam can help the dental team assess your gums and discuss appropriate next steps; it cannot be replaced by a description of symptoms online.
