If you’re a new patient, you’ll probably undergo dental X-rays to get a clear picture of your dental health. This is especially important if you don’t have any X-rays from your previous dentist.
While dental X-rays do involve radiation, the exposed levels are so low that they’re considered safe for children and adults. If your dentist uses digital X-rays instead of developing them on film, your risks from radiation exposure are even lower.
The dentist will also place a lead “bib” over your chest, abdomen, and pelvic region to prevent any unnecessary radiation exposure to your vital organs. A thyroid collar may be used in the case of thyroid conditions. Children and women of childbearing age may also wear them along with the lead bib.
Pregnancy is an exception to the rule. Women who are pregnant or believe they may be pregnant should avoid all types of X-rays.
