Radiographs (x-rays)

Radiographs are an important part of a dental exam. Cavities that form in between the teeth are sometimes undetectable in the mouth and can only be seen by x-ray. We recommend yearly bitewing x-rays. We also recommend a full mouth set of x-rays or panorex be taken once every five years. This allows us to visualize the roots of each tooth, look for dental infections, and evaluate bone levels, root canals, fillings and crowns that are already in your mouth. We understand that you may be concerned with the amount of radiation you are exposed to during dental x-rays. Based on research the amount of radiation you receive during dental x-rays is minimal, much less than any medical x-rays and slightly more than you receive from being outside on any given day.
