Many pregnant or breastfeeding women are reluctant to visit the dentist out of fear that radiation exposure might harm their babies. Fortunately, this is usually not the case - as studies have shown that radiation from dental X-rays is relatively small and has minimal effect on the foetus if any. Both the American Dental Association and American Pregnancy Association have stated that dental X-rays shouldn't be avoided because of risk-related concerns. Even so, most dentists will choose to avoid taking an X-ray during pregnancy unless it's necessary - a testament to how seriously professionals take their responsibility in caring for expectant mothers and their children.
