Why do dentists take x-rays?

• We do x-rays to do a proper examination – what the eyes can’t see they can’t treat. X-rays reveal:
o Cavities and holes, under old fillings and between the teeth and under the gum line
o If there is bone loss between the teeth – that can lead to gum disease and loss of teeth
o If there are any hidden pathology, like oral cancer and the start of abscesses
