We recommend taking x-rays around the age of two or three. The first set consists of simple pictures of the front upper and lower teeth, which familiarizes your child with the process. Once the baby teeth in back are touching each other, then regular (at least yearly) x-rays are recommended. Permanent teeth start coming in around age six, and x-rays help us make sure your child’s teeth and jaw are healthy and properly aligned. If your child is at a high risk of dental problems, we may suggest having x-rays taken at an earlier age.
