The images taken from dental X-rays provide your dentist with valuable information about your teeth and gums and help him or her plan the best treatment for any problems that you have.
Of course, the machines used for dental X-rays do involve radiation, but the amount of exposure is extremely small, which is why studies have shown that dental X-rays are safe for most people in most situations.
In fact, measurements of the radiation in dental X-rays show that they are not significantly different from the radiation most people are exposed to in daily life from environmental influences. These might include frequent travel by airplane and certain appliances in the home, such as TV sets and smoke detectors.
Although the amount of radiation in dental X-rays is quite low and the procedure is safe, pregnant women should refrain from dental X-rays unless they are necessary. But because pregnant women are at increased risk for gum disease, it’s important not to ignore a potentially serious dental problem due to fears about radiation exposure from X-rays. If you are pregnant and you require dental X-rays, your dental professional will have you wear a lead apron and a lead thyroid collar to protect vulnerable areas. In fact, children and women of childbearing age should wear protective lead coverings when getting dental X-rays. But there is no added risk associated with dental X-rays for breastfeeding women or women who are trying to become pregnant.
