Traditional veneers typically require the removal of a small portion of tooth enamel to ensure a proper fit. For porcelain veneers, about 0.5 mm of enamel is shaved off, and a slightly lesser amount for composite veneers​​. However, there are minimal or no-prep veneers like Lumineers, Durathin, and Vivaneers which may not require the teeth to be shaved down​.
