What are veneers and crowns?
A Veneer is a thin layer of porcelain which is applied to the front of the tooth only and is used to disguise discolouration, heavily broken teeth where cosmetic bonding is not a viable solution and as a fast way to achieve a radiant and beautiful looking smile.
A Crown is a ceramic or occasionally precious metal cap which covers the tooth entirely and is used in similar situations to dental veneers, however where there is less of the original tooth available, usually requiring the tooth to be filed down so that the crown can be fitted. Crowns are also used to complete your smile following the placement of a dental implant.
For the most part, no. If your teeth are already well aligned then the veneer can simply be applied to the front of the tooth but in some cases there may need to be adjustments made to the tooth.
No, veneers and crowns are usually made from porcelain which will not discolour, dependent on what you eat and drink, like your natural teeth do.
No, veneers and crowns cannot be whitened. However as veneers and crowns will not discolour like your natural teeth, whitening may be required to bring your teeth back to the same colour as your veneers or crowns the longer they are in place.
