Are Dental X-Rays Safe?

Share this to Friends

Oftentimes patients ask us, “Are dental x-rays safe?”

There are a lot of misconceptions as well as legitimate health concerns about dental X-rays.

First, many patients do not realize there are different types of X-rays and imaging techniques. And that, X-rays radiation dose varies depending on the type of x-ray being taken.

When considering whether you need a set of dental X-rays, it may help to weigh the pros and cons.

Benefits of Dental x-ray

Dental X-rays provide us with information that we use to safely and accurately detect hidden dental abnormalities and complete an accurate treatment plan. Without x-rays, some problems may go undetected.

Dental X-rays use very low levels of radiation. And in most cases dentists seek to follow a protocol of “As Low As Reasonable Achievable” (the ALARA principle).

At Smile Avenue we use the latest technology that involves the use of an electronic sensor (instead of x-ray film) that captures and stores the digital image on a computer. This image can be instantly viewed and enlarged helping us to detect problems easier. Digital x-rays reduce radiation by as much as 80-90% compared to the already low exposure of traditional x-rays.

We also use a protective lead apron whenever we take xrays

Be sure to inform your Smile Avenue Specialist Dentists if you are pregnant or trying to conceive. Also, let them know about any other concerns you may have.

Comparing Dental X-rays radiation To Other Sources Of Radiation

Keep in mind that we naturally experience radiation from minerals in the earth. All organic matter including humans, animals, and vegetables contain carbon and potassium which happen to be radioactive.  While it is impossible to avoid natural radiation, you may still want to avoid excessive radiation exposure. As Smile Smile Avenue,  we think the potential life-saving benefits of occasional dental X-rays far outweighs the risk of the minimal radiation exposure involved in a set of X-rays.

Estimated dental X-ray radiation dose.

  1. Old-school film based dental X-ray – .5 mrem
  2. One digital dental X-ray – .08 mrem
  3. A set of four Bitewings – .4 mrem

An mrem refers to a “Millirem” which is the unit X-rays are measured by.

Notice more modern imaging techniques like digital X-rays reduce the dose.

Since we realize that radiation is all around us, let’s compare the radiation exposure in mrem from other sources:

  • Flying in an airplane – .5 mrem per 30 minutes of flight.
  • Smoking a daily pack of cigarettes – 36 mrem per year
  • A mammogram screening – 42 mrem per breast
  • Cooking using natural gas – 10 mrem per year
  • Watching television or using a computer – 1 mrem per year
  • Drinking water and eating food – 30 mrem per year
