If your gums bleed when you brush or floss your teeth, you might shrug it off or think this is normal. But bleeding from the gums indicates an underlying problem.

Factors like brushing too vigorously, injury, pregnancy, and inflammation can contribute to bleeding gums. Gum inflammation can cause redness, swelling, and tenderness, and it can be a sign of periodontal disease, such as gingivitis or periodontitis. Such disease can occur from inadequate plaque removal.

Identifying the cause of bleeding gums is key to determining the most appropriate treatment. Once you know the cause, you can choose among these 10 possible ways to stop the bleeding.

1. Practice good oral hygiene

Bleeding gums may be a sign of poor dental hygiene.

Gums become inflamed and bleed when there’s a buildup of plaque along the gum line. Plaque is a sticky film containing bacteria that covers your teeth and gums. And if you don’t brush or floss enough, the bacteria can spread and cause tooth decay or gum disease.

To improve oral hygiene, brush your teeth at least twice daily and floss once a day. Here are more tips for keeping your teeth healthy.

Good oral hygiene is especially important for pregnant women. Hormone fluctuations during pregnancy can also trigger gum disease and bleeding gums.

2. Rinse your mouth with hydrogen peroxide

You might keep hydrogen peroxide on hand to use as a disinfectant. Turns out it can also remove plaque, promote gum health, and stop gum bleeding. If your gums are bleeding, rinse your mouth with hydrogen peroxide after brushing, but don’t swallow the solution.

Gingivitis is an inflammation of the gums, and this condition can cause bleeding, swelling, and receding gums. In a of 99 subjects, some were given a mouth rinse of hydrogen peroxide to study the effectiveness of the solution on reducing gingivitis and whitening teeth. The study found that the group that rinsed with hydrogen peroxide had less gum inflammation than the control group.

3. Stop smoking

In addition to heightening the risk of lung cancer, heart disease, and stroke, smoking is linked to gum disease. In fact, smoking is a major cause of severe gum disease in the United States, says the .

Smoking can lower your body’s immune system, making it harder for your body to fight off plaque bacteria. This can lead to gum disease.

Quitting smoking can help your gums heal and stop bleeding. Talk to your doctor about the best method to help you quit smoking.

4. Reduce stress level

One suggests a link between periodontal disease and emotional stress. According to the researchers, emotional stress has a negative impact on the immune system. This may result in weakening of the body’s defenses to the point where it can’t fight a gum infection. However, more research is needed to determine the amount of stress that can trigger the onset of this disease.

It’s believed that emotional stress may also cause some people to neglect their oral health, which can contribute to the accumulation of plaque. Find out some of the things you can do to relieve stress.

5. Increase your intake of vitamin C

Eating foods rich in vitamin C can strengthen your immune system and help fight off the gum infections that cause bleeding gums.

Conversely, not getting enough vitamin C in your diet may worsen bleeding if you have gum disease. In fact, a vitamin C deficiency can also lead to gum bleeding even if you practice good oral habits.

Foods rich in vitamin C include:

  • oranges
  • sweet potatoes
  • red peppers
  • carrots

You can also ask your doctor about taking a vitamin C supplement. As a powerful antioxidant, vitamin C strengthens connective tissue and protects the lining of your gums, so you’ll want to be sure you’re getting enough each day. The recommended daily amount of vitamin C for adults is between .

Foods rich in vitamin K include:

  • spinach
  • collard greens
  • kale
  • mustard greens

The recommends that adult men get 120 micrograms and women get 90 micrograms of vitamin K daily.

7. Apply a cold compress

Bleeding gums aren’t always caused by gum disease. Your gums may also bleed from trauma or an injury to the gum tissue.

A can reduce swelling and restrict blood flow to stop bleeding. Apply an ice pack or a cold cloth to your gums several times a day, 20 minutes on and 20 minutes off.

8. Eat fewer carbs

has found that reducing your carbohydrate intake may also improve gum health and prevent gum disease. Carbohydrates and sugary foods encourage plaque and the growth of bacteria. The more plaque accumulated on your gums, the more likely you are to have bleeding gums.

Although brushing and flossing regularly can reduce this buildup, cutting back on carbs helps prevent plaque formation.

9. Drink green tea

Drinking green tea on a daily basis may also reverse periodontal disease and stop bleeding gums. Green tea contains catechin, a natural antioxidant that can lower the body’s inflammatory response to bacteria in the mouth.

One of 940 men analyzed the effectiveness of green tea on improving periodontal health. For the study, researchers examined the periodontal pocket depth of participants before and after drinking green tea, as well as any loss of gum tissue and incidences of gum bleeding by probing. Based on the results, researchers concluded that the more green tea a person drinks, the better their periodontal health.

The recommended daily intake of green tea is three to four cups, although some researchers believe that you need to drink up to to notice any improvement in health.

10. Rinse your mouth with salt water

Because bacteria and inflammation in the mouth causes gum disease, regularly rinsing your mouth with a may also reduce bacteria and stop gum bleeding.

Add half a teaspoon of salt to a glass of warm water and rinse your mouth for a few seconds three to four times a day. If bleeding is from an injury or trauma, rinsing with a salt water mixture also keeps your mouth clean and removes bacteria that could cause a wound infection.
