X-rays are necessary to detect decay between teeth and areas not visible to the naked eye. Gum and bone problems happen slowly over time, so they are often not felt or detected from the surface.
X-rays detect bone loss and infections at root surfaces.
Understandably, many people's concern is excessive radiation exposure.
Adler Advanced Dentistry takes digital radiographs, which release 90% less radiation, than conventional techniques (which most of us seemed to have survived!)
