What is wrong with your crown? If you just don't like the way it looks and there is substantially good tooth under it, then most commonly a dentist will just replace the crown with a new one.
If the tooth is a poor candidates for a new crown, then you could consider removing the tooth and placing either a fix bridge or single tooth implant.
An implant with a new crown will cost about the same as a fixed bridge, and the bridge may be covered by dental insurance, while the implant may not be. Also, placing a new crown will probably be about 1/3 the cost of doing an extraction, implant placement and implant crown.
