My DS (7) has had 4 X rays now over the years for different things. He's recently had to have a dental x ray of his mouth because one of his emerging teeth has damaged the roots on another teeth which isn't due to be lost until he's quite a bit older. It has shown that he is going to need allot of orthodontic work. I know that he'll have to have more X rays etc and was a bit worried that he's already had quite allot. What do you think?
