question: Hi doctor, I have constant pain in my front tooth (11). I have not had any trauma to it as of I aware and I take good care of my teeth. I do not have gum disease. There may be a tiny bit of gum recession due to over brushing. The ache is constant. I do not get any pain from cold or hot food or drinks. When I eat the pain seems to disappear, but it is present when I am not doing anything. I can feel it as pulsatile pain. Please help.
