Many of my patients arrive to their appointment with questions and concerns about dental x-rays. Dental x-rays are very safe compared to medical x-rays. The amount of radiation is relatively low.
An interesting fact is that every day we are exposed to radiation. Everything in our environment gives off a certain amount of radiation. For example the sun gives off a certain amount of radiation but you wouldn’t spend your life avoiding sunlight. Unless you are a vampire. All joking aside, dental x-rays are one of the lowest doses of radiation within the medical field. In a routine exam, we take 4 bitewing x-rays which is .005 mSv. This is less than 1 day of natural background radiation. It is the same amount of radiation when you fly in a plane for 1-2 hours.
You may be wondering, “Why does my dentist need to take dental x-rays?” Dental x-rays are helpful for many reasons. They help us find decay inbetween teeth that may not be visible to the naked eye. X-rays also help us check for bone loss, cysts, abscesses, infection on the root, and decay under fillings. Dentists may also need to get an x-rays of the bones and teeth before any procedures they perform and to diagnose periodontal disease.
Dental x-rays are a safe, and important part of dental care. X-ray technology helps find dental issues at an early stage, which saves patients time, money and discomfort.
