Why do gums bleed?
Plaque is a soft, sticky film of bacteria that forms on teeth every day. When it isn't cleaned away along the gumline, the gums react with inflammation: they become red, puffy and bleed easily when brushed or flossed. This early, reversible stage is called gingivitis.
If plaque stays, it hardens into tartar, which can't be brushed off and keeps irritating the gums. Over time, inflammation can spread below the gum and damage the bone that holds the teeth — this is periodontitis, or gum disease.
What else can make gums bleed?
Plaque is the most common cause, but other factors can contribute:
- Brushing too hard or using a hard-bristled brush
- Starting to floss after a long gap (bleeding usually settles within a week or two of regular flossing)
- Hormonal changes, especially during pregnancy
- Diabetes, particularly when blood sugar is not well controlled
- Smoking — which can also hide bleeding by reducing blood flow to the gums
- Blood-thinning medicines and some other medications
- Poorly fitting dentures, braces or a rough filling edge that traps plaque
- Less commonly, nutritional deficiencies or blood disorders
Should I stop brushing if my gums bleed?
No — this is one of the most common mistakes. Bleeding usually means the gums are inflamed by plaque, and the answer is to clean more thoroughly but gently, not less. Avoiding the area lets more plaque build up.
- Brush twice a day for two minutes with a soft brush, angled towards the gumline.
- Clean between your teeth once a day with floss or interdental brushes.
- Use fluoride toothpaste and spit rather than rinse.
- If you smoke, stopping is one of the best things you can do for your gums.
Is it gingivitis or gum disease?
Only a dental examination can tell, because gum disease often causes no pain. A dentist measures the small pockets between the gums and teeth and may take X-rays to check the bone. Signs that point towards more advanced gum disease include:
- Gums pulling back, making teeth look longer
- Teeth that feel loose or have shifted
- Pus between the teeth and gums
- Persistent bad breath or a bad taste
- Changes in how your teeth fit together when you bite
How is it treated?
Gingivitis usually improves within a couple of weeks of a professional cleaning and good home care. Gum disease needs deeper cleaning below the gumline, sometimes in several sittings, followed by regular maintenance visits. More advanced cases may need minor gum surgery. Gum disease can't always be fully reversed, but it can usually be controlled to protect the teeth.
Are bleeding gums linked to general health?
Research has found associations between gum disease and several general health conditions. The link is clearest with diabetes, where it appears to work both ways: poorly controlled blood sugar makes gum disease more likely, and untreated gum inflammation can make blood sugar harder to control. Studies have also reported associations with heart disease and with pregnancy complications, although these links are still being researched and do not prove that one causes the other.
Either way, healthy gums are part of looking after your overall health, and treating gum disease is worthwhile in its own right.
When should I worry?
See a dentist if bleeding hasn't settled after about two weeks of careful brushing and cleaning between teeth, or sooner if you notice any of the warning signs above.
See a doctor promptly as well if bleeding gums come with unexplained bruising, nosebleeds, bleeding that's hard to stop elsewhere, unusual tiredness, or fever — these can point to a medical cause that needs checking. If you are pregnant or have diabetes, mention gum bleeding to your doctor and dentist.

Common questions
It's common when you start flossing after a gap, and it usually settles within one to two weeks of daily flossing. If it doesn't, have your gums checked.
Gingivitis can usually be reversed with a professional cleaning and good home care. Advanced gum disease can be controlled with treatment and regular maintenance.
Severe vitamin C deficiency can, but it is uncommon. Plaque is by far the most common cause. A dentist or doctor can check if another cause is suspected.
Hormonal changes in pregnancy can make gums more prone to inflammation. Dental check-ups and cleaning are generally considered safe in pregnancy — tell your dentist you are pregnant.
