The porcelain veneer is very strong and should not break under normal circumstances. If gum recession occurs the root of the tooth may become exposed. Patients may want new veneers to cover the roots. The integrity of veneered teeth is marginally compromised, and the veneer is bonded to the existing teeth. There is no higher incidence of decay provided that the veneers are properly cared for as detailed above, regular brushing with toothpaste, and flossing.
