I've have my front four teeth crowned recently & they are just a bit too long. I'm really worried about getting them shortened because I don't want to mes them up. They are already cemented in. I have already had them redone once. I'm happy with everything about them but the length. My dentist told me to wear a few days & if I still wanted yo take a bit off...he could. It just scares me because I don't want to mess them up cause I can't afford to have them cut off & redone again. Thank you.
