Bleeding gums: causes and when to see a dentist
Why gums bleed when you brush, how early gum disease can be reversed, and the signs that need a dental visit.

Gums that bleed when you brush or floss are not normal, even if it doesn’t hurt. The most common cause is gingivitis — early gum inflammation caused by plaque along the gumline.
Why it happens
Plaque is a soft film of bacteria that builds up every day. If it isn’t removed, the gums become red, puffy and tender, and they bleed easily. Over time plaque hardens into tartar, which brushing alone cannot remove.
Other things that can play a part
- Brushing too hard or starting to floss after a long break
- Pregnancy and other hormonal changes
- Diabetes and some medicines
- Smoking, which can hide bleeding while gum disease progresses
The good news
Gingivitis can usually be reversed. A professional clean removes tartar, and gentle, thorough brushing twice a day with daily cleaning between the teeth lets the gums settle, often within a couple of weeks.
Signs to get checked soon
- Bleeding that continues for more than a week or two despite good cleaning
- Gums that are pulling back from the teeth
- Persistent bad breath or a bad taste
- Teeth that feel loose or are changing position
