Dental X-Rays are the only means by which practitioners are provided with the information they need to establish a proper diagnosis. Periodic x-rays are recommended once a year and allow the dentist to evaluate for dental caries in-between your teeth. At our office digital x-rays are used, which utilize 90% less radiation than conventional x-rays did years ago. Some patients may be concerned about radiation dose received from dental x-ray exposure. Keep in mind that the 4 bite-wing x-rays that are taken once a year to screen for cavities and pathology, equate to less than the average daily dose of radiation from our environment.
