9 Causes of Bleeding Gums When You Brush Your Teeth

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.Red, swollen, bleeding gums are another common sign of vitamin C deficiency. Without adequate vitamin C, gum tissue becomes weakened and inflamed and blood vessels bleed more easily. In advanced stages of vitamin C deficiency, gums may even appear purple and rotten.
