Call your dentist and tell her/him that you are pregnant .It may be possible to have the crowns seated without anesthetic,depending on your pain tolerance and if the tooth has a root canal,you will definately not need any numbing.Your dentist may want to talk with your ob/gyn to get clearance for anesthetic.If needed.Just tell your dental office ahead of time so they can plan what is best for you.Good luck with your pregnancy!!
