Seeing blood when you brush or floss can be easy to dismiss, especially if it happens only occasionally. But healthy gums are generally firm and resistant to bleeding. Bleeding can be an early sign that the tissues supporting your teeth need attention, and a dental assessment can help identify the cause before the problem becomes more difficult to manage.
This guide explains common reasons gums bleed, what you can do at home, and when to contact a dentist in Ottawa. It is general information, not a diagnosis.
Why do gums bleed?
Plaque is a soft, sticky film that forms on teeth every day. When it collects along the gumline, the gums can become inflamed, red or puffy. This early stage of gum disease is called gingivitis. The Public Health Agency of Canada notes that blood on a toothbrush or floss can be a symptom of gingivitis.
If plaque is not removed, it can harden into tartar (calculus). Brushing and flossing cannot remove hardened tartar; a dental professional may need to remove it. Untreated inflammation can progress to periodontitis, which affects the gums and bone supporting the teeth.
Bleeding can also be influenced by a recent change in flossing habits, brushing too aggressively, pregnancy-related hormonal changes, smoking, diabetes, certain medications or other health conditions. Because several causes can look similar at home, persistent or unexplained bleeding deserves a professional assessment.
When should you book a dental visit?
Book an appointment if your gums bleed almost every time you brush or floss, if the bleeding continues despite gentle daily care, or if you notice red, swollen or tender gums. The Canadian Dental Association recommends seeing a dentist when bleeding happens nearly every time you clean your teeth.
Arrange an assessment promptly if bleeding appears with any of these changes:
- persistent bad breath or an unpleasant taste;
- gums pulling away from the teeth;
- pus, increasing swelling or significant tenderness;
- a loose tooth or a new space between teeth;
- pain when chewing; or
- bleeding that is spontaneous, heavy or difficult to stop.
Heavy bleeding that will not stop, facial swelling that is spreading, trouble breathing or swallowing, or a serious injury requires urgent care. Call the dental office for guidance and seek emergency medical help when symptoms are severe.
What happens during a gum assessment?
A dentist will review your symptoms, home-care routine, medications and relevant health history. The examination may include looking for plaque and tartar, checking the colour and firmness of the gums, and gently measuring the spaces between gums and teeth. Dental X-rays may be recommended when needed to assess the bone supporting the teeth.
The findings guide the next step. Early gingivitis may improve with professional cleaning and more effective home care. More advanced gum disease may require additional treatment or referral. The plan should be based on your examination rather than assumptions made from bleeding alone.
What can you do at home?
Continue cleaning your teeth unless a dental professional has told you otherwise. Stopping because of mild bleeding allows more plaque to remain. Brush for about two minutes twice a day with fluoride toothpaste and a soft-bristled toothbrush. Clean gently along the gumline rather than scrubbing hard. Clean between teeth daily with floss or another interdental aid recommended for you.
If you are beginning to floss after a long break, a small amount of bleeding can occur at first. It should not be ignored if it is frequent, worsening or persistent. Do not try to scrape away tartar with household tools, and avoid relying on mouthwash to mask ongoing symptoms.
Smoking can increase the risk and progression of gum disease and may make signs less obvious. If you smoke or use tobacco, tell your dentist. Also mention pregnancy, diabetes, blood-thinning medication or any recent medication change; do not stop prescribed medication without speaking with the prescriber.
