Can Dental X-Rays Cause Cancer?
When it comes to dental care, patients often question the safety of dental X-rays. Concerns about radiation exposure and cancer risks are common.
Our Alexandria dentist, Dr. Mullaney, answers your questions about whether dental X-rays can cause cancer here.
What Are Dental X-Rays?
Dental X-rays are essential tools in modern dentistry, allowing dentists to peer beyond the surface of your smile. Using low levels of radiation, these imaging tests capture detailed pictures of your teeth, gums, and jawbone, revealing hidden issues that may not be apparent during a routine exam.
How Often Should You Get Dental X-Rays?
It depends on your age, oral health, and other risk factors. The American Dental Association (ADA) recommends full mouth X-rays (FMX) for adults every three to five years. However, Dr. Mullaney may suggest more frequent X-rays if you have specific dental concerns or require dental procedures.
Bite wing X-rays are typically taken once a year, even for adults who have good oral health. This is because bitewing X-rays can detect cavities and other problems that may not be visible on a full mouth X-ray.
Children may need X-rays more often due to their developing teeth and jaws. The American Academy of Pediatric Dentistry (AAPD) recommends that children receive their first dental X-rays between the ages of 3 and 6.
Are Dental X-Rays Safe?
The short answer is yes. While it’s true that X-rays emit radiation, the amount used in dental procedures is extremely low and considered safe for most individuals. In fact, the radiation exposure from a dental X-ray is significantly less than what we receive from natural sources like the sun or certain foods.
Can Dental X-Rays Cause Cancer?
Numerous studies and reputable organizations have confirmed that the risk of developing cancer from dental X-rays is extremely low.
According to the US Department of Energy, exposure to 10,000 millirem (mrem) of radiation would only increase the chances of cancer by 1%. A dental X-ray exposes a person to approximately 2-3 mrem of radiation.
Furthermore, a research report that was widely misinterpreted in 2012 suggested a link between dental X-rays and brain tumors. However, the actual findings of the research demonstrated no increased risk of brain tumors associated with dental X-rays. The NHS also debunked this link.
Benefits of Dental X-Rays
- Early detection and prevention: X-rays can detect hidden dental problems before they become major issues. They can reveal cavities between teeth, infections in the bones, tumors or cysts, impacted teeth, and changes in the jawbone. Detecting these issues early allows for prompt treatment and prevents further complications.
- Planning procedures: X-rays provide dentists with a clear picture of your teeth and jawbones to plan more precisely. This is particularly important for complex procedures like tooth extractions, root canals, and orthodontic treatments.
- Monitoring growth and development: For children and adolescents, X-rays are invaluable in tracking the development of their teeth and jaws. They allow dentists to assess tooth growth, identify potential issues early on, and ensure proper eruption.
- Improving accuracy: Digital X-rays offer superior image quality, allowing dentists to see small details more clearly. This improves the accuracy of diagnoses and treatment decisions.
