Why do I need an x-ray

Dental radiographs (x-rays) show the structures of your teeth and mouth that cannot be seen visually during your clinical examination. We routinely take x-rays every 2-3 years to check for decay. Some areas of your teeth have thicker outer enamel surfaces making detection of decay, by looking clinically only, very difficult. X-rays also allow us to see the very early signs of decay which means we can start treatment early – sometimes without having to do a filling!
From time to time there are other more specific reasons to take an x-ray, for example, infection or to check on wisdom teeth. Dental x-rays require small radiation doses (even smaller now that we have digital x-rays!) however, we never take them unnecessarily.
