You should let your OB doctor know all about this. I didn't have this same issue but I did have to have a bunch of dental work done in my 7th month during my first pregnancy. I guess it's a big deal if you have any tooth infections because it can hurt the baby. I think you should contact your OB ASAP.
I did and they act like its no big deal . I was reading that the puss is toxic so I brought it up to the dentist and he said no you'll be fine im wondering if its hurting during labor will they give me anything for the pain or just keep me in on vicodin idk
Get the tooth out. Even if you went into labor right in the dentist's chair, it's much better for it to be gone. Tell your ob-gyn also, since they might want you to be on antibiotics for this reason. Good luck!!!
