If you must have dental work or diagnostic tests, tell your dentist or your physician you are pregnant so extra care can be taken with you. Dental X-rays are necessary sometimes and can be done during pregnancy. Your abdomen must be shielded with a lead apron before X-rays are taken. If possible, wait until after the end of the first trimester to have any dental work done. Avoid gas or general anesthesia for a dental procedure during pregnancy.
Local anesthetics are OK, and so are many antibiotics and pain medications.
Be sure to consult your healthcare provider before taking any medications. A serious dental problem, such as an abscess, must be treated. Problems that could result from not treating it are more serious than the risks you might be exposed to with treatment. Some men get jealous of all the attention given to the woman and her developing baby. New maternity clothes, baby toys and equipment, and conversations with friends or family often center around the pregnancy, making him feel left out.
