With my first pregnancy, my upper left wisdom tooth reared its ugly head, and the shitty dentist I used said that my swollen mouth was because I needed a root canal on my farthest back molar. He never finished the root canal and it shattered and had to be pulled, and then my stup is wisdom tooth actually did it's job and filled the empty spot. But now with my new pregnancy my lower left wisdom tooth has me all swollen and in pain. I guess I'll have to go get it pulled, but it just sucks. Anyone else have teeth problems when pregnant?
