There is nothing to worry so much. Teeth cleanings and dental X-rays are safe for pregnant women, as most dental X-rays don’t affect the abdomen or pelvic area. Most of gynecologist encourage their patients to see a dentist during pregnancy to maintain their oral hygiene. However the level of safety depends on the type of X-ray you need and exactly how much radiation you are going to be exposed to. Most diagnostic X-rays do not expose the fetus to high levels of radiation to cause a problem. Although, remember one thing that greater your exposure is to radiation, the greater the risk could be to your baby. So do not worry at all. Go for the regular check-up to your doctor. All the best. Take care.
