As compassionate and well-informed dental professionals at Metro Decatur Dental Group PC, we understand that many of our patients have concerns regarding radiation exposure from dental x-rays. In this article, we aim to provide clarity and address the importance of this diagnostic tool and its impact on your health.

Minimizing Radiation Exposure

Let’s begin by emphasizing that dental x-rays involve significantly lower radiation exposure compared to other types of diagnostic x-rays. For instance, the common “bite-wing” x-rays we take during your regular preventive care routine expose you to even less radiation than panoramic x-rays. So, rest assured that the most frequently used x-ray type has minimal impact in terms of radiation exposure.

Putting It in Perspective

To put things in perspective, the radiation dose from a bite-wing x-ray session is only slightly more than the amount of radiation we naturally encounter in our daily lives on Earth. The Earth’s solar radiation and trace amounts of naturally occurring radioactive elements, like radon, contribute to our background radiation exposure.

Measuring Radiation Exposure

Radiation doses are measured in microsieverts, and on average, a person receives approximately 0.8 microsieverts from natural sources each year. An intraoral x-ray exposes you to about 5.0 microsieverts, equivalent to approximately 6 days’ worth of natural radiation. To put this into context, it is comparable to the amount of radiation exposure experienced during a 2-hour flight on an airplane.

Personalized X-Ray Frequency

At Metro Decatur Dental Group PC, the frequency and type of x-rays we recommend for your mouth depend on your individual oral health needs. Some patients may have specific risk factors that necessitate more frequent x-rays to monitor their oral health closely. Rest assured, our decision to take x-rays is always based on your well-being.

The Importance of Dental X-Rays

While the small doses of radiation from dental x-rays are highly unlikely to impact your health, the absence of this vital diagnostic tool could have more significant consequences. Dental x-rays enable us to visualize hidden aspects of your oral health that remain invisible to the naked eye and cannot be assessed through any other means.
