Simply put, the health risk associated with avoiding periodic x-rays greatly exceeds the health risk of taking those x-rays.
Risk from periodic dental x-rays is extremely small. Radiation exposure is measured in a unit called the “millisievert” (mSv), which represents the amount of radiation energy absorbed by the body. According to the Mayo Clinic, there is no convincing epidemiological evidence of increased cancer incidence or mortality at low doses (<100 mSv) — long-term effects are either too small to be observed or are non-existent.
Every year in the U.S., we’re exposed to 3 mSv of natural background radiation that occurs in the environment. Digital dental x-rays expose us to approximately 0.005 mSv, which is equivalent to approximately half a day’s worth of natural background radiation.
Risk from avoiding periodic x-rays is much larger. Undetected cavities can lead to potential tooth loss, root canals, and crowns; gum disease can progress and lead to potential loss of teeth.
We will only recommend x-rays that we deem to be clinically necessary, and will follow protocols to minimize exposure.
