Porcelain veneers are able to significantly improve the appearance and colour of teeth that are discoloured or chipped. Veneers are a thin semi-translucent "shells" of porcelain permanently bonded to your teeth. Veneers are extremely strong and wear resistant. A pleasant natural look can be achieved from veneers with little or no discomfort as a very small amount of tooth structure is removed for the porcelain to cover the tooth during its application. A common pre-requisite for porcelain veneers is that your gums should be healthy as this will enable the dentist to get an accurate fit for the veneer at the gum line.
