A. Hi, thanks for your question, it would only be possible to consider replacing the crowns if you still have the root. Your denture may have been placed over the root, but the root may have been removed. Without this information, it would be difficult to say. If the root remains, it may be possible to have a post crown, however if you no longer have the root, the options to replace would be either a bridge (which would be attached to the healthy teeth on either side of the gap) or an implant (which could support a new crown). I hope that this information will be of assistance to you, but should you require further information, please do not hesitate to contact me again.
Kind Regards
