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.
Bitter taste in mouth is a common side effect of many medications. It could be due to infection of gums or cavities in teeth. It could also be an abnormal perception of bitter taste called dysgeusia. GERD and heart burn too cause metallic taste in mouth. Post nasal drip as in sinusitis, salivary glands infection, pharyngitis or strep infection too are common causes.
