Hi all, i recently gave birth and 4 weeks in to the pregnancy i was told that i needed root canal work on my upper back tooth. Last week i went to the dentist as i was in pain and he took out the filling and packed it with some stuff and put a temporary filling over it and booked me in for root canal work on the 20th. It no longer hurts but feels a bit dodgy, i get a few twinges every now and then. Any way i just felt my gum and right at the top where it joins my cheek i have a small hard bump the size of an O when i press on it it doesnt hurt but it kind of feels like its putting pressure of my tooth. I get a very odd feeling in my teeth. What do you think this is? unless i had gone poking around i wouldnt have noticed it and i cant feel it with my tongue. any advice?
