Certain dental procedures, like an extraction,a root canal treatment or a dental implantation requires a dental x-ray to be taken. The reason for this is that these procedures involve the portion of the mouth that is not visible, the parts below the gum line.

Concern over environmental factors in causing cancer is growing. Many seemingly harmless things (water bottles, grilled vegetables, etc) are now being labelled as carcinogenic, and are being shunned. X-rays have long been known to be carcinogenic, as the x-ray machine emits gamma radiation in controlled doses. Are dental x-rays bad for you? Can they contribute to cancer?
