If they are just going to do novacaine for the procedure and give you antibiotics to prevent infection it SHOULD be ok. I had 8 teeth pulled 2 weeks before I delivered my first pregnancy. I also had a wisdom tooth cut out at 8 months with my 3rd pregnancy. Just be sure to discuss it with your doctor and make sure you don't have any risk factors that would prevent it.
I would check with your doctor. I had a tooth ache about 3 weeks ago, and the dentist wouldn't even touch me! I had to go through my OB for antibiotics and he didn't want me to go to the dentist. All dr's & patients are different, but my first step would be to contact your doctor.
