According to the ShareCare website, dental x-ray examinations only expose you to very small amounts of radiation. The average dose of radiation is about .005 millisieverts. By comparison that is the typical amount of radiation exposure that you receive from the sun every day. Dr De Vizio DMD of Colgate says “there are no significant risks…” however, he goes on to say that “…pregnant women should be sure to tell their dentist that they are pregnant and avoid taking any dental x-rays…” Well, if there is a risk to pregnant women shouldn’t we all be concerned? Radiation is radiation right? Shouldn’t we try to avoid as much radiation as possible.
It is important for your dentist to be able to use x-ray exams in order to see issues with bone and tissues that he can not see with the naked eye. The radiation exposure is very low according to the ADA and you can use a thyroid collar for extra protection. If you see your dentist on a regular basis you probably do not need x-rays but once a year.
