Are X-Rays Safe?

Some patients are afraid to get an  X-ray at the dentist’s office because they’ve heard the radiation from these tests is unsafe. But, the truth is, dental X-rays are very safe and should be no cause for concern.

How Safe Are X-Rays?

The American Dental Association considers the risk of X-rays to be “very small”, especially if using digital x-rays. X-rays introduce some radiation to the body to produce images, but the dose is so low that the possibility of harmful side effects is extremely unlikely. 

Since dental health affects the rest of your body, the potential benefits of detecting undiscovered disease far outweighs any small risk involved.

How Much Radiation Is in an X-Ray?

Radiation is measured by a unit called millisieverts (mSv). You are exposed to about three millisieverts of natural background radiation each year. 

As a comparison, here are some typical radiation doses from dentistry:

  • Bitewing X-Ray: 0.005 mSv
  • Panoramic Dental X-Ray: 0.025 mSv
  • Cone Beam CT Scan: 0.18 mSv


This means that the most common dental X-ray provides a lower radiation dose than you receive naturally from just being outside on a typical day.

Why Do Dentists Use X-Rays?

Dentists use X-rays to find dental problems and gum-related issues that are not always obvious during a visual oral exam. X-rays help dentists identify cavities, bone loss, cancer, abscesses and tumors, and infections under the gums that would otherwise go undetected as well as changes in previous root canals, and help prepare for dentures and implants.

An X-ray can also show your dentist the overall state of your teeth, helping them to create a dental plan that keeps your teeth in good shape.

At Piper Family Dentistry, we make sure to follow the “as low as reasonably achievable” (ALARA) principle with our X-rays, which means that you won’t get any more scans taken than required.

I've been a patient of Dr. Piper's for the last 19 years so it's very obvious that I've been a very very satisfied patient. I had an excellent full check-up today with x-rays and everything was perfect. Perfect because I've been going consistently and following their experts on dental care, cleaning and good health! Bravo 👏 👏 👏

Dr. Piper and staff are always very professional, I have been a patient for over 15 years, and happy about it. Just got my teeth cleaned and checked recently, Sandra is friendly and thorough, and the office felt very clean which is important.

Staff were fast and attentive, didn't wait long before I saw Dr. Piper. The office is clean and organized. Was a great decision to use this practice and will be visiting again. Not a single issue. Cannot recommend enough.
