I had a tooth pulled on October 31rst, I went to my dentist last week because I was still in pain, he said I had a little bit of dry socket so he put some kind of nasty tasting cream there, well now I have a blood blister right in the hole where my tooth was pulled, it's very painful and I can't get into the dentist until Tuesday, I'm afraid to eat because I'm afraid I will pop the blood blister. the dentist office couldn't answer any of my questions over the phone, is this normal, could it have something to do with me smoking?
