Dental X-Rays Radiation Exposure: What You Need To Know

Answers to Concerns about Dental XRay Radiation Pella, IA

The Importance of Dental X-Rays

Dental x-rays are an essential aspect of maintaining good oral health. They help dentists diagnose and treat a range of dental issues, from cavities to gum disease. X-rays provide detailed images of your teeth, gums, and jawbone, which helps dentists identify problems that may not be visible during a visual exam.

However, many people are concerned about the radiation exposure associated with dental x-rays. Radiation exposure can increase the risk of cancer, and it’s important to understand the risks and benefits of dental x-rays.

The Risks of Radiation Exposure

Radiation exposure can be harmful to the body, and the level of risk depends on the dose and duration of exposure. The risk of developing cancer from radiation exposure is generally low, but it can increase with higher doses of radiation and repeated exposure over time.

While dental x-rays do expose you to radiation, the amount is extremely low. A single dental x-ray exposes you to about the same amount of radiation you would receive from a few hours of natural background radiation. In comparison, a CT scan exposes you to significantly more radiation.

Reducing Radiation Exposure

There are several ways to reduce your radiation exposure during dental x-rays. First, make sure your dentist uses digital x-rays instead of traditional film x-rays. Digital x-rays use significantly less radiation than film x-rays.

Second, your dentist should only take x-rays when necessary. The frequency of x-rays depends on your age, dental health, and other factors. Generally, adults without any dental issues should have x-rays every two to three years, while children may need them more frequently.

Protecting Yourself During X-Rays

Your dentist will provide you with a lead apron to wear during x-rays. This apron helps shield your body from unnecessary radiation exposure. Additionally, your dentist may use a thyroid collar to protect your thyroid gland from radiation exposure.

If you’re pregnant, it’s important to let your dentist know. While dental x-rays are generally safe during pregnancy, your dentist may choose to delay non-emergency x-rays until after your baby is born.


Dental x-rays are an essential tool for maintaining good oral health. While they do expose you to radiation, the amount is extremely low and the risk of harm is minimal. By following these tips, you can further reduce your radiation exposure during x-rays and protect your overall health.
