Why do my gums bleed when I brush my teeth?
If your gums frequently bleed while you are brushing or flossing your teeth, it may indicate the presence of gum disease. As gum disease progresses, bacteria spreads throughout the gum line and forms deep periodontal pockets. These pockets cause the gum line to pull from the surface of teeth. Gums become irritated, inflamed, and sensitive to the touch.
Brushing and flossing can agitate the already sensitive and inflamed gum tissue causing them to bleed!

Gum disease is common and occurs in patients of all ages. Fortunately, you can prevent and manage it by improving your oral hygiene routine and getting professional teeth cleanings from Dr. Patel. However, not all patients with bleeding gums have gingivitis or gum disease. Some other reasons why your gums bleed when you brush your teeth may include:
- Aggressive brushing is one of the most common reasons that cause bleeding gums. Brushing your teeth too hard or using a hard-bristled toothbrush can bother your gums and create microscopic cuts.
- Lack of a good oral hygiene routine is another common reason. By not brushing and flossing regularly, such as on a daily schedule, you are not removing plaque and bacteria along the gum line as best as you can. This can and will lead to gum inflammation and bleeding.
- Although not as common, a change to your oral care routine can cause bleeding gums. For example, using a new toothbrush, floss, or mouthwash can “shock” your gums while they adjust to the change.
- Sometimes medications, such as blood thinners or anticoagulants, can make your gums more prone to bleeding
- Some doctors believe that vitamin deficiencies, particularly vitamin C and K, can make your gums weak and cause them to bleed easily.
- Hormonal changes during pregnancy or other times of hormonal fluctuations can increase blood flow to your gums. This can make them more sensitive and prone to bleeding.
- A bad diet lacking in essential nutrients and high in sugar can cause inflamed gums. The inflammation makes them more likely to bleed.
- Lastly, some medical conditions, like diabetes, leukemia, and immune disorders, can affect gum health and increase the chances of bleeding.

Bleeding Gums Treatments in Claremont, CA
At Claremont Dental Institute, our dentists screen for gum disease as part of our routine dental exams. We provide comprehensive periodontal treatment options for restoring health to smiles affected by all stages of gum disease. Our dentist determines the course of treatment by the overall health of the patient’s smile as well as the stage and progression of the gum disease. We combine dental technology, laser therapy, and deep cleanings to help stop bleeding gums and rebuild healthy, stable, beautiful smiles for our patients.
Healthy gums are essential for a stable, functional smile. Gum tissues help to hold teeth in place and protect the tooth root from exposure or damage. But when gum disease takes hold, it compromises the gum tissue and causes the gum line to recede. Our dentists offer painless laser treatments to promote healing and recontour the gum line, and repair damage caused by gum disease.
Without treatment, gum disease can begin to impact your bodily health. Gum disease has been associated with a higher rate of cardiovascular disease, inflammation, heart attacks, and strokes. Patients with diabetes or those who are obese have a higher risk of developing gum disease.
Patients with gum disease are more prone to:
- Chronic halitosis
- Tooth loss
- Receding gum line
- Tooth sensitivity
- Patchy red or white spots on their gums
- Swollen, tender gums
Bleeding Gums FAQs
Bleeding gums are very common, but can lead to serious consequences. We’ve collected and answered some of the most frequently asked questions about bleeding gums below.
Is it normal for gums to bleed when I brush or floss?
While occasional bleeding can happen if you’ve just started flossing again after a break, it’s not normal for gums to bleed regularly. Frequent bleeding is a sign that your gums are inflamed or infected. This inflammation may indicate early gum disease, also known as gingivitis. If you notice consistent bleeding, it’s best to schedule a dental checkup to stop the issue before it progresses.
Can brushing too hard cause my gums to bleed?
Yes, brushing too aggressively or using a toothbrush with hard bristles can irritate the gums and cause them to bleed. It can also wear down the enamel on your teeth over time. Using a soft-bristled toothbrush and gentle circular motions is usually enough to clean effectively without causing trauma. If your gums continue to bleed despite gentle brushing, a dental exam is recommended.
Why are my gums bleeding around a tooth after a fall?
Bleeding around one tooth could suggest a dental injury, such as falling, an impact to your mouth, or an accident. The force can cause the tooth to become loose, get pushed further into its socket, or even fall out. However, it can be a very early sign of gum disease. If your gums are bleeding around one single tooth, it can be the first sign of inflammation from a bacterial infection.
Are bleeding gums common in children?
Bleeding gums can occur in children, especially if they are not brushing or flossing properly. Poor oral hygiene and plaque buildup are the most common causes. However, it can also signal early gum disease or nutritional deficiencies. If your child’s gums bleed frequently, schedule a dental visit to assess the cause and reinforce good hygiene habits.
When should I see a dentist about bleeding gums?
You should see a dentist if your gums bleed frequently or for more than a few days, especially if accompanied by swelling, bad breath, or receding gums. These symptoms could indicate gum disease, which requires professional care. The earlier it’s treated, the easier it is to reverse or control. Even if you think the bleeding is mild, it’s better to be cautious and have your gums evaluated.
How can I prevent bleeding gums in the future?
Prevention starts with a consistent oral care routine: brushing twice daily, flossing once a day, and visiting the dentist every six months. Use a soft-bristled toothbrush and avoid harsh brushing techniques. Eat a nutritious diet, avoid tobacco, and drink plenty of water to keep your mouth healthy. Staying consistent with your hygiene and dental visits greatly reduces the risk of gum problems.
Preventing Gum Disease, Maintaining Oral Wellness
Brushing and flossing twice daily for two full minutes is your first defense against the build-up of disease-causing oral bacteria. Daily oral hygiene removes debris and food particles and reduces the build-up of plaque and tartar on the surface of the teeth. Bacteria thrive off of plaque, multiplying and spreading throughout the oral cavity. Brushing and flossing well interrupt this cycle and help to manage oral bacteria.
Routine dental health exams are also important in preventing oral disease. Routine visits allow our dentists to diagnose gum disease as soon as possible to prevent further deterioration of your gums, and damage to your teeth and jaw.
Professional teeth cleanings can help clear out plaque and tartar buildup in hard-to-reach spaces between your teeth. Your dental hygienist will thoroughly clean all surfaces of the teeth and gums. We suggest to have your teeth professionally cleaned every six months to keep your oral health in the best condition possible.
