Bleeding Gums When Brushing: Causes, Treatment and When to Worry
Bleeding gums are common but not normal. Learn the most likely causes, how to fix them at home, and when to see a dentist.
Quick answer
Gums that bleed when you brush are most often caused by gingivitis, an early, reversible gum inflammation caused by plaque. Brushing gently twice a day, cleaning between teeth daily and having a professional cleaning usually stop the bleeding within two weeks. See a dentist if bleeding continues beyond two weeks, or if gums are swollen, receding or painful.
Seeing pink in the sink after brushing is common, so many people ignore it. But healthy gums shouldn't bleed. Bleeding is your body's signal that the gums are inflamed.
What causes bleeding gums?
- Gingivitis (most common): plaque along the gum line irritates the gums, making them red, puffy and prone to bleeding.
- Brushing too hard or using a hard-bristled brush.
- Starting to floss: gums often bleed for the first few days, then settle.
- Periodontitis: advanced gum disease, where inflammation damages the bone holding the teeth.
- Pregnancy: hormone changes make gums more sensitive ("pregnancy gingivitis").
- Diabetes: poorly controlled blood sugar raises the risk of gum disease.
- Medicines: blood thinners and some other medicines can increase bleeding.
- Smoking: it damages gums, and can hide bleeding while disease gets worse.
- Rarely: vitamin deficiencies or blood disorders.
Gingivitis vs periodontitis
| Gingivitis | Periodontitis | |
|---|---|---|
| What's affected | Gums only | Gums and supporting bone |
| Signs | Red, swollen, bleeding gums | Receding gums, loose teeth, bad breath, pus |
| Reversible? | Yes, fully | Damage can be stopped but bone loss is permanent |
| Treatment | Better cleaning at home + professional clean | Deep cleaning and regular gum maintenance |
How to stop bleeding gums at home
- Brush twice a day for two minutes with a soft brush, angled towards the gum line.
- Clean between your teeth every day with floss or interdental brushes. Keep going even if it bleeds at first.
- Rinse with warm salt water to soothe the gums.
- Eat a balanced diet with fruit and vegetables.
- Stop smoking.
If gingivitis is the cause, bleeding usually improves within one to two weeks.
When should you see a dentist?
Book a check-up if:
- Bleeding lasts more than two weeks despite good brushing
- Gums are swollen, painful or pulling away from teeth
- Teeth feel loose or your bite has changed
- You have persistent bad breath or a bad taste
See a doctor promptly if you also bruise easily, have nosebleeds or feel unusually tired. These can point to a medical cause.
Frequently asked questions
Should I stop brushing if my gums bleed?
No. Stopping lets more plaque build up and makes it worse. Brush gently but thoroughly.
Can bleeding gums be a sign of diabetes?
Gum disease is more common and more severe in people with diabetes. If you have bleeding gums along with thirst, frequent urination or tiredness, ask a doctor about a blood sugar test. See our article on diabetes check-ups.
Will a dental cleaning stop my gums bleeding?
A professional teeth cleaning removes the tartar that keeps gums inflamed. Combined with good home care, it usually resolves gingivitis.
