Noticing blood when you’re brushing or flossing your teeth can be alarming. It seems like a bad sign. You immediately want to know, “Why are my gums bleeding?”
Try not to stress too much. There are a few different reasons your gums may be bleeding, and the fix could be as simple as adjusting your brushing and flossing technique. What’s important is identifying the cause of the bleeding so you can address it if necessary.
Depending on the root cause, you may need to see a dentist to address your gum problems.
Why Are My Gums Bleeding?
Lots of people experience bleeding gums occasionally. Gums are sensitive soft tissues packed with blood vessels, so it doesn’t take much to make them bleed a little1.
Bleeding gums are not necessarily a cause for concern, but you do want to consider the reason why it’s happening. The only way to know how to stop bleeding gums is to understand the cause.
For example, you could bite into something sharp that presses into your gums, causing some bleeding. The cause of the bleeding could also be brushing too hard. In both cases, the bleeding will usually stop quickly as your gums heal and toughen up. Sometimes, though, what causes bleeding gums is gum disease or other issues that you should address so they don’t worsen.
Common Causes of Bleeding Gums
If you notice your gums bleeding when brushing, consider whether it’s due to one of these common causes.
Gingivitis and gum disease
One reason gums may bleed is due to gum disease. Gingivitis is the earliest stage of gum disease, when plaque and tartar build up and cause inflammation in the gums.2 You may not even realize you have gingivitis initially because it’s typically painless. Bleeding from the gums is a warning sign to take seriously.
Gingivitis generally follows this progression2:
- Plaque forms on your teeth after you eat.
- If not removed quickly with daily brushing and flossing, plaque turns into tartar, which can’t be removed with just brushing.
- The part of your gums around your teeth—called the gingiva—becomes irritated by the plaque and tartar. This gum irritation leads to swelling and sometimes bleeding.
The good news is that gingivitis is reversible. Going to see the dentist and implementing good oral health habits, like brushing your teeth twice a day and flossing daily, can reverse gingivitis and stop the bleeding.
If left unaddressed, however, gingivitis can lead to periodontitis, a more severe gum disease that affects the tissues and bones in your mouth2. Periodontitis is when your gums pull away from your teeth, creating small pockets between them where bacteria can erode the supporting tissue. Your teeth may become loose and even fall out if you don’t get treatment for periodontitis3.
Brushing too hard, flossing, and other causes
Seeing bleeding gums when brushing does not necessarily mean you have periodontitis or gingivitis, though. Brushing or flossing too hard could also be to blame.
The bristles of your toothbrush may irritate your gums and cause some bleeding, especially if you’re brushing roughly or using a hard-bristled brush. Similarly, flossing with force can make your gums bleed.
Other possible causes of bleeding gums include4:
- Smoking
- Taking blood thinners
- Nutrient deficiencies, such as low vitamin C or vitamin K
- Diabetes
- Hormone fluctuations (including during pregnancy)
- Bleeding/clotting disorders
- Stress
More than one factor may be contributing to your gums bleeding, so if the issue persists, make an appointment with your dentist to investigate further.
How to Stop Bleeding Gums
Most of the time, irritation is what causes bleeding gums. To stop the bleeding, you need to find the source of that irritation and address it.
Try these approaches:
- Switch to a soft-bristle toothbrush.
- Brush your teeth gently at least twice a day.
- Floss gently once daily.
- Rinse your mouth with an antibacterial mouthwash after eating.
- Avoid smoking.
- Visit your dentist every six months for regular cleanings.
- Make a dentist appointment right away to address concerning bleeding.
Depending on the cause of the bleeding, your dentist may recommend a deep cleaning, medication, or surgery for severe periodontitis.
When Bleeding Gums Are a Warning Sign
Bleeding gums are a warning sign of potential gum disease if the bleeding continues for more than a few minutes after brushing or becomes persistent4.
You should also make an appointment with your dentist if you notice bleeding alongside pain or visible gum swelling. If your teeth are loose, contact your dentist right away.

Frequently Asked Questions
Is it normal for gums to bleed when brushing?
It’s normal to have a little bleeding occasionally when you brush your teeth, especially if you’re using a hard-bristled brush or brushing very roughly. Use a soft-bristle brush to gently clean your teeth instead.
What’s not normal is daily bleeding or bleeding from the gums that doesn’t stop quickly. These are signs that there may be an issue with your gums, so see a dentist. Severely swollen gums or loose teeth, along with bleeding gums, also mean you should make an appointment with your dentist.
How do I stop my gums from bleeding?
The best way to stop your gums from bleeding depends on the underlying issue. If your gums are bleeding when brushing or flossing, try switching to a soft-bristled toothbrush. Brush gently around the gums, and don’t be too forceful when flossing. It may take about a week for your gums to become less inflamed, so they don’t bleed from this new routine.
However, bleeding due to gum disease generally needs to be treated by a dentist to help make it stop. Your dentist will clean your teeth professionally and may prescribe medication or surgery to treat the gum disease, depending on how far it’s progressed.
Do bleeding gums always mean gum disease?
No, bleeding does not always mean you have gum disease. There are several other possible causes of your gum bleeding, including a harsh brushing and flossing routine, vitamin deficiencies, ill-fitting mouthguards or dentures, and smoking.
Try adjusting your brushing and flossing to start. If a gentler routine stops your gums from bleeding, you were probably just cleaning your teeth too harshly. If the bleeding persists, consider contacting your dentist to investigate further and develop an action plan to address the underlying issue.
Can bleeding gums heal on their own?
Yes, bleeding gums often heal on their own. If the bleeding comes from brushing, flossing, or a superficial wound, it should stop and heal within a few days. However, sometimes the bleeding continues. In that case, you should make an appointment with your dentist to figure out why your gums are bleeding and what you can do about it.
When should I see a dentist about bleeding gums?
Go to the dentist if your gums are bleeding for extended periods or bleeding every day (even for just a little while). Also, if your gums are painful or swollen or your teeth are loose, it’s best to go see your dentist. These symptoms are all signs of possible gum disease, which requires intervention from a dentist to prevent further damage.
