Sometimes when i eat cold foods, like popsicles i will bleed where i have a missing tooth (I just lost one the other day). I always think its just my gums, but just recently my tooth was bleeding & i spit from my throat & blood & spit also came out. Is this because i have a very dry nose and a history of frequent nosebleeds? Should i worry about this? This is happened only about two times but I am getting worried. I am probably overreacting but it is hard to explain to my Mother. Please give advice.
