Fun Fact Friday: "A Dental X-Ray Exposes You To 7 Times Less Than Radiation Than A 2 Hour Flight"
When patients hear the word “radiation,” it often causes unnecessary concern. However, modern dental X-rays are among the safest medical imaging tools used today. The amount of radiation is extremely small—comparable to everyday sources we barely notice. For example:
Eating a banana exposes you to natural radiation from potassium; a single dental X-ray delivers about the same amount as eating a few bananas.
Spending a few minutes in sunlight actually exposes you to more radiation than a dental X-ray.
A short airplane flight exposes you to several times more radiation than a full set of dental X-rays.
Advances in technology have made dental X-rays even safer. Older film-based X-rays required higher radiation doses, but today’s digital sensors reduce exposure by up to 90% while producing clearer, more detailed images. These improvements help dentists catch problems earlier and treat them more effectively.
Dentists also take multiple safety measures to protect you, including using lead aprons, thyroid collars, and strictly following the ALARA principle—keeping radiation “As Low As Reasonably Achievable.” This means X-rays are only taken when necessary for diagnosis or treatment planning, never without a clear purpose.
In short, the radiation from dental X-rays is minimal, carefully controlled, and far outweighed by the benefits of early detection. Rather than posing a risk, dental X-rays are a vital tool for maintaining your teeth, jaw, and overall health.
