Are xrays necessary?

Absolutely. Dental xrays are essential, preventative, diagnostic tools. Many oral conditions occur between teeth or under the gums or bones, undetectable by the human eye, and may have no early signs or symptoms. Left untreated, these conditions can create serious dental and general health problems, including loss of teeth and heart problems. Early detection with xrays can make treatment much less painful, faster, and less expensive. The American Dental Association recommends getting a full series every three years.
