Bleeding between teeth when brushing
Bleeding between teeth often reflects inflamed gums around plaque, but recurring bleeding can also signal gum disease or another local problem.
The short answer
Gum bleeding between teeth most often reflects inflammation caused by plaque at the gum edge or between teeth. It can also follow vigorous cleaning, trapped food, a rough filling, or periodontal disease.

What is the direct answer?
What does this question mean?
The interdental papilla is the small gum peak between teeth. Inflammation makes its blood vessels more prone to bleeding, so stopping interdental cleaning can leave the irritant in place.
What can you do next?
Use a soft brush with gentle pressure and clean between the teeth daily with floss or a correctly sized interdental brush. A dentist or hygienist can remove calculus and check gum pockets or restoration edges.
When should you seek dental care?
Seek care if bleeding recurs, gums swell, teeth loosen, or pus or persistent bad breath appears. Urgent care is needed for facial swelling, fever, swallowing difficulty, or bleeding that will not stop with pressure.
What should you ask the dentist?
Ask whether the cause is gingivitis, periodontal disease, calculus, decay, or a restoration. Ask which interdental tool and technique fit your teeth.
Frequently asked questions
Could this have more than one cause?
Yes. Several oral tissues or materials can produce similar symptoms, so examination may be needed to distinguish them.
What should I record before an appointment?
Note when it began, where it occurs, what triggers it, and any swelling, bleeding, sensitivity, discharge, or appliance change.
