The most common cause of gums bleeding when you brush is gingivitis — inflammation caused by plaque and hardened calculus at the gumline. In most cases a single scaling appointment (৳1,000–2,000) plus correct brushing stops the bleeding within one to two weeks.
Healthy gums don't bleed
Many people assume a little blood when brushing is normal. It isn’t. Healthy gums are pink, firm, and don’t bleed when brushed. Bleeding means there is inflammation.
The main cause: plaque and calculus
A soft sticky film — plaque — forms on teeth after eating. If it isn’t cleaned off properly it hardens into calculus within 24–72 hours. Calculus cannot be brushed away, and the bacteria on it keep the gum inflamed. The result is red, swollen gums that bleed easily.
Other causes
- Brushing incorrectly: a hard brush used with force wears the gum back and makes it bleed.
- Vitamin C deficiency: uncommon, but real. Keep citrus, guava and amla in the diet.
- Pregnancy: hormonal changes make gums far more reactive (pregnancy gingivitis).
- Diabetes: uncontrolled diabetes accelerates gum disease and slows healing.
- Blood-thinning medication: always tell your dentist if you take any.
- Smoking and paan: these reduce blood flow to the gums, so damage increases while visible bleeding decreases — which delays diagnosis.
The biggest mistake
Because it bleeds, many people stop brushing that area. This is the worst possible response. Without brushing, more plaque accumulates, inflammation increases and the bleeding gets worse. The area needs to be cleaned gently, with a soft brush — not avoided.
What to do at home
- Use a soft brush and small circular movements, without pressure
- Twice a day, two minutes each time
- Floss or use an interdental brush once daily — a brush cannot reach between teeth
- Warm salt-water rinses reduce inflammation
- Replace your brush every three months
When you first start brushing properly, bleeding may briefly increase. That is expected and should settle within one to two weeks.
When to see a dentist
If bleeding hasn’t reduced after two weeks of correct brushing, there is almost certainly calculus present — and only scaling removes it. Don’t delay if you also notice:
- Swollen gums or pus discharge
- Teeth starting to feel loose
- Gums receding so teeth look longer
- Persistent bad breath
Gingivitis is completely reversible. Left untreated it becomes periodontitis, where the bone around the tooth is destroyed — and that bone does not grow back.

In most cases, yes. Once the calculus is removed the inflammation subsides, and bleeding usually stops within one to two weeks provided brushing is also corrected.
Yes — scaling is safe in pregnancy, and the second trimester is the most comfortable time for it. Tell your dentist you are pregnant before the appointment.
If the cause is only soft plaque, correct brushing can resolve it. Once hard calculus has formed it cannot be brushed off, and it will not resolve without scaling.
