I have had veneers on 8 of my top and 6 bottom teeth 10 years ago before my wedding. However as my bite is the wrong way round ie my bottom teeth coming over my top when my jaw is clenched together, the upper veneers occasionally come off. i would like them replaced with crowns as they bulge here and there also in comparison to the remaining teeth. What would be the likely costs of replacing all of my veneers with crowns please? I want them a more natural colour and also a more natural shape than what I have at the moment but of course still white!
