A little pink in the sink is easy to ignore, but healthy gums do not usually bleed. Here is what bleeding gums are often telling you, what helps, and when to ask a professional.
Common causes of bleeding gums
Gums bleed when the tissue is inflamed or irritated. In most cases the cause is simple and fixable, and it starts at the gumline where plaque collects.
- Plaque building up along the gumline
- Brushing too hard, or using a stiff-bristled brush
- Starting to floss again after a long break
- Hormonal changes, including pregnancy
- Some medications, such as blood thinners
- Dentures or braces that do not fit or clean well
Plaque and gingivitis
Plaque is a soft, sticky film of bacteria that forms on teeth throughout the day. If it is not cleaned away it irritates the gums, which become red, swollen and prone to bleeding. This early stage is called gingivitis.
Gingivitis is common and reversible. With consistent cleaning at home and a professional clean, gums usually settle within a couple of weeks. Left alone, it can progress to periodontitis, a more serious gum disease that affects the tissue and bone supporting your teeth.
Brushing and flossing
Good technique matters more than force. Use a soft-bristled brush and angle it gently towards the gumline, brushing for two minutes twice a day with fluoride toothpaste.
Clean between your teeth once a day with floss or interdental brushes. If your gums bleed when you start, keep going gently: bleeding from inflamed gums often eases within one to two weeks of regular cleaning.
When should you see a dentist?
Book an appointment if bleeding continues for more than a couple of weeks after improving your routine, or if you notice any of the following:
- Gums that are persistently red, swollen or tender
- Bad breath that does not go away
- Gums pulling back from your teeth
- Loose teeth or a change in how your teeth fit together
- Bleeding that is heavy or happens without brushing
A dentist can remove hardened plaque (tartar) that brushing cannot, check for gum disease and rule out other causes.
How can you prevent bleeding gums?
- Brush twice a day with a soft brush and fluoride toothpaste
- Clean between your teeth daily
- Have regular check-ups and professional cleans
- Limit sugary snacks and drinks between meals
- Tell your dentist about any medications or health changes
Frequently asked questions
Is bleeding gums normal?
It is common, but it is not a sign of healthy gums. Occasional bleeding often points to plaque or a change in routine. If it keeps happening, it is worth having checked.
Can brushing too hard cause bleeding?
Yes. Hard brushing or a stiff brush can irritate the gums and wear them back over time. Switch to a soft brush and use light, circular strokes.
How long should bleeding gums last?
When caused by plaque, gums often improve within one to two weeks of thorough, gentle cleaning. If bleeding lasts longer, see a dentist.
Should I see a dentist if my gums bleed?
If bleeding persists beyond a couple of weeks, comes with swelling, soreness or bad breath, or you are unsure why it is happening, a dental check-up is the best next step.
