A dental veneer is a layer of material placed over the front of a tooth for either aesthetic reasons or to protect a tooth from further damage. There are two main types of material used to fabricate a veneer; ceramic/porcelain and composite resin.
Professional teeth whitening/bleaching can be done in-chair or at-home.
External tooth bleaching involves applying a concentrated gel of either hydrogen peroxide or carbamide peroxide onto the tooth surfaces with custom-made trays. This can be done in the comfort of your own home with the professional take-home kit.
