If the tooth is mostly solid, you can apply tooth colored bonding material and it will look quite natural. If the tooth is more damaged but relatively stable, you can place a porcelain veneer. If the tooth is relatively week, a porcelain cap might be necessary.
Veneers are excellent to reshape teeth, close spaces, and change colors.
Despite all the bold claims, we haven't seen any significant whitening results with toothpastes or even the mail order whitening kits. The most consistant whitening results occur with our home bleaching kits and our in office laser bleaching , or a combination of both. What are porcelain veneers and why are they cosmetically preferred to caps. Unlike caps that require much tooth reduction or preparation, veneers require minimal preparation and are very conservative. Since they have no metal in them, they are cosmetically superior over porcelain to metal crowns.
