We will likely take sets of X-rays during your treatment to see how it is progressing, and after treatment to assess its outcome. The types of X-rays we will need depend on your treatment plan. However, all of these X-ray methods emit low levels of radiation—less than you would receive when being screened for an airline flight—and are very safe and free of side effects. #xrays #orthodontics
