How often does my family need x-rays?

This is a tricky question because the truth is that the answer varies greatly depending on not only your age, but your dental and overall health and whether you are prone to any particular dental problems. On average, x-rays every 12 - 24 months are typically appropriate, but we may recommend them more frequently for: 

  • Children
  • Adolescents
  • People with periodontal disease
  • People who are prone to cavities
  • People undergoing orthodontic treatment

We will also recommend x-rays if a specific problem is suspected such as an infection or if an injury has occurred and we need to determine the extent of damage. 

We only perform x-rays as frequently as is necessary to maintain your dental health. We also use digital x-rays, which help to minimize your radiation exposure, and appropriate protective equipment, including lead shields.

Your health is important to us, and we take it very seriously. Dental x-rays use a tiny amount of radiation, especially compared to other medical x-rays and procedures that use radiation such as mammograms and CT scans. We truly believe that the small amount of radiation exposure is worth it for the valuable information that x-rays provide. We prefer to use the least invasive, most conservative option whenever it exists, and dental x-rays make that possible.
