You need to go to the dentist! You don't need any kind of infection, especially in your mouth. They can pull wisdom teeth during pregnancy I'm sure they can do something for you!don't just take Tylenol and ignore it:P
I had a really bad toothache for about a week and then after that it was a constant dull pain for a couple of months. The best advice I have is to try the dentist. Not sure if they'll be able to do anything, I just stuck it out scared to take anything other Tylenol which doesn't help at all
