Patients often ask why do I need x-rays and are they safe? Dental x-rays are taken for many reasons and the frequency they are needed is different for each individual. Your dentist will access your risk factors along with your dental history to determine when they will prescribe x-rays for you.  Without these images your dentist would be unable to detect cavities between teeth, infections or defective crowns or bridges. Your dentist may also be looking for missing teeth, impacted teeth and even an abnormal growth that may occur in the bone.

Radiation exposure can occur by acute or chronic exposure. Acute exposure is a large dose in a short period of time and a chronic exposure is a small dose over a long period of time. All of us are exposed to radiation everyday. This is referred to as background radiation and is naturally occurring. One single x-ray is 20-30 times less than the annual amount of background radiation and 50-300 times less than a single CT scan. New digital x-ray machines decrease the radiation exposure even more. Unnecessary x-rays are filtered out and the x-ray beam is focused to the area of interest but as an extra safety precaution a lead apron shields your body. 

At Rideau dental centre, your overall health is important to us. Our dentists only recommend the x-rays they feel you need and that is safe for you
