What the risks are:

There is very low radiation exposure. However, no one should receive more radiation than necessary. A lead apron can be used to cover the body and reduce radiation exposure. Pregnant women should not have x-rays taken unless absolutely necessary.

Special considerations:

Dental x-rays can reveal dental cavities (tooth decay) before they are visible even to the dentist. Many dentists will take yearly bitewings to catch the early development of cavities.

Another imaging test, called cone beam computerized tomography (CBCT), may be used prior to dental surgery, especially when multiple implants are being placed. This test is usually done in a hospital or imaging center.
