Radiographs or x-rays are used in every dental office. They are a great way to see the teeth and bones and make sure they are healthy. In the past, x-rays were taken using little pieces of covered film. They were placed in the mouth and exposed using an x-ray machine. They always jabbed inside the mouth and seemed to take forever to be processed. Well, those days are now behind us! In the new era of dentistry, dentists are using digital radiography.
