Important to stop bleeding gum when brushing teeth

The simple act of brushing your teeth irritates the swollen gums, and makes them bleed. If you don't treat bleeding gum, not only will you slowly lose all of your teeth, but it may affect your health.

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.

Increase your intake of vitamin K
Taking a vitamin K supplement may also alleviate bleeding gums. Vitamin K is an important nutrient because it helps your blood clot. A deficiency can cause easy bleeding, and one study found that it may lead to gum bleeding.
Foods rich in vitamin K include:
spinach
collard greens
kale
mustard greens
The Office of Dietary Supplements recommends that adult men get 120 micrograms and women get 90 micrograms of vitamin K daily.

stop eating carbohydrate
Reducing your carbohydrate intake 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.
