The dental profession, however, says otherwise. Annual preventive X-rays, called bitewings, for healthy dental patients are not necessary.
Of course, for adults whose dental health is not as ideal, listening to your professional’s advice makes a great deal of sense. Adults prone to cavities, for instance, should have bitewings done every year-and-a-half, states the ADA, depending on the individual’s overall dental picture.
Reducing exposure to radiation also can be a consideration as to whether or not have annual X-rays. Without being alarmist, and without demonstrating absolute certainty, studies focusing on radiation accumulation have pointed to avoiding low-level exposure. And with its own recommendations, the ADA concurs.
“Even though radiation exposure from dental radiographs is low,” citing from the report, titled, Dental Radiographic Examinations: Recommendations For Patient Selection and Limiting Radiation Exposure, “once a decision to obtain radiographs is made it is the dentist’s responsibility to follow the ALARA Principle (As Low as Reasonably Achievable) to minimize the patient’s exposure.”
Finally, x ray taken by portable dental x ray unit reveal more than what your dentist can see when s/he peers into your mouth, and for some people the possibility exists that tooth decay, once it starts, can spread quickly. So if you’re the type who tends to operate with an abundance of caution – and possibly, an unnecessary abundance – then accept your dentist’s offer for annual X-rays.
