Bleeding Gums Stress can cause a reaction from bacteria inside of your mouth that make your gums bleed. Blood happens to tastes like metal, and can be tasted even if the amount of blood is barely perceptible. It's possible that during anxiety attacks and stress, you're experiencing a minor gum bleed.
