When I had my shoulder smashed and my right side, I had to remove everything on my arms and body and my necklace. No piercings though. Probably depends where you get x rayed would help for helpful comments. :d
That sounds odd, that they let you keep your piercings. I know for sure you have to remove any jewelry and accessories. But, when it comes to retainers.... not too knowledgeable on the subject. I would assume it would be okay to wear retainers, as long as the retainer isn't on the area that is going to be x-rayed, but I want to make sure.
Well my shoulder and arms and chest don't have any piercings. Actually. Let's step back a minute because I do have nipple piercings buuuut my accident was on horseback in which I do not wear them so no, I had no piercings in.
