Dental anesthesia in early pregnancy

Last week, I had my tooth prepared for a crown. This involved quite a bit of anesthesia into the gum surrounding my tooth. This morning, I discovered I was about five weeks pregnant. Is it possible that the anesthesia at this early stage will harm my baby?


Receiving dental treatment during pregnancy is not considered to be taboo anymore. In fact, regular checkups and cleanings are recommended by the American Dental Association.

The local anesthetic should not worry you. In fact, a very low percentage of obstetricians surveyed wish to be consulted prior to administration of local dental anesthetic.

The main concerns are X-rays and certain medications that might be prescribed during the course of dental treatment. X-rays during pregnancy, especially during the first trimester, should be kept to an absolute minimum. The antibiotics we generally use in dentistry, penicillin and derivatives thereof, are usually fine for the developing fetus. Special attention should be taken when prescribing analgesics, however.

While receiving dental care during pregnancy generally presents no problem to the developing fetus, elective dentistry, such as routine X-rays, teeth whitening, etc. should be postponed until after the baby is born.
