If you’ve ever noticed a little pink in the sink after brushing or flossing, you’re not alone. Bleeding gums are more common than you might think, and they can be your body’s way of saying, “Hey, something’s up!”

Sometimes it’s as simple as brushing too hard. Other times, it’s a sign that your gums need a little extra care. Let’s explore the 15 most common causes of bleeding gums, what they mean and how to get your gum health back on track.

15 Reasons Your Gums Bleed

There are many reasons you might notice bleeding from your gums; some are easy fixes, while others may need a dentist’s help.

Here are the most common causes of bleeding gums:

1. Plaque buildup: When plaque isn’t brushed or flossed away, it irritates the gums and causes inflammation and bleeding.
2. Gingivitis: The early stage of gum disease, gingivitis makes gums red, swollen and prone to bleeding.
3. Brushing too hard: A heavy hand or stiff-bristled toothbrush can damage delicate gum tissue.
4. Flossing inconsistently: If you don’t floss regularly, gums may bleed when you suddenly start again. This is because flossing eliminates the plaque that builds up between the teeth. When this is inconsistently removed, the gums remain inflamed and irritated.
5. Medications: Blood thinners and certain prescriptions can increase gum bleeding.
6. Poor oral hygiene: Skipping brushing or dental checkups allows bacteria to build up, leading to inflammation.
7. Vitamin C deficiency: Low vitamin C can weaken gums, leading to swollen, bleeding gums.
8. Vitamin K deficiency: This vitamin helps your blood clot, so a lack of it can make gums bleed easily.
9. Hormonal changes: Pregnancy, menstruation or menopause can make gums more sensitive and prone to bleeding.
10. Tobacco use: Smoking or chewing tobacco irritates gum tissue and slows healing.
11. Diabetes: High blood sugar can weaken your gums’ ability to fight infection, leading to bleeding.
12. Ill-fitting dental appliances: Dentures or braces that rub can cause localized gum bleeding.
13. Infections: Viral or fungal infections can cause bleeding in gums around one or more teeth.
14. Dry mouth: Saliva protects your gums. When your mouth is too dry, bacteria multiply and cause irritation.
15. Stress: Chronic stress affects your immune system, making your gums more vulnerable to inflammation and bleeding.

What Does It Mean When Your Gums Bleed?

Occasional bleeding—especially when you’ve just started flossing again—is expected. It’s often a sign that your gums need a little extra TLC. When you see bleeding, that’s not a sign to back off, it’s generally a sign to be more consistent with your oral health routine.

But if your gumsbleed often, or you notice bleeding around one tooth, it could mean something more serious. Persistent gum bleeding may point to gingivitis (another word for gum disease), periodontal disease (advanced gum disease) or even a systemic health issue like diabetes, autoimmune diseases, hormonal changes, blood disorders, leukemia or a vitamin deficiency.

So, what can cause bleeding gums? Anything from poor brushing habits to health conditions that affect your body’s healing and immune response.

And what can bleeding gums mean? That your gums need attention, either from your toothbrush or your dentist.

Prevent Bleeding Gums Before They Start

Healthy gums don’t just happen; they’re the result of consistent care. Try these simple habits to keep your smile healthy and your gums happy:

• Use a soft-bristled toothbrush and brush with gentle, circular motions.
• Floss daily to prevent plaque and bacteria from settling in.
• Rinse with an antimicrobial mouthwash to reduce bacteria.
• Eat a vitamin-rich diet full of fruits, veggies and lean proteins.
• Stay hydrated. Saliva is your mouth’s natural defense.
• Avoid sipping acidic beverages like energy drinks, throughout the entire day. Limiting frequency ensures that you are not prolonging the exposure of your teeth and gums to acid liquids which erode enamel, cause dry mouth and harm your teeth and gums.
• Visit your dentist every 6 months for a check-up and cleaning.

When to See Your Dentist

A little bleeding every now and then isn’t unusual, if your oral care is inconsistent. However, frequent or persistent gum bleeding isn’t something to ignore. Early treatment can prevent gum disease and protect your overall health.

If you’ve noticed teeth bleeding for no reason, or your gums are swollen and sore, schedule a dentist appointment. Your dentist can help find the cause, treat it and get you smiling again.
