Looking at the crowns, they do not look horrible; actually, they look pretty good. However, good is a relative term. If you were looking for awesome white flawless teeth, then the crowns are a huge fail. But if you had stains or chipped teeth previously, then your crowns are great. My advice would be to be as specific as possible about exactly what you do not like about the crowns, so that you can describe this to your dentist. If he/she offers any guarantee or warranty on work done, then you may be able to get a replacement or a redo at no cost. If no such guarantee is offered, then there may be a charge, depending on the circumstances and how long you have had them. Hurry back to your dentist because you have a much better chance of working things out if you don't wait several weeks from the date they were first placed. Good luck and I hope this helps.
