When preparing for veneers, only a minimal amount of tooth enamel is removed to make room for the veneers while ensuring they stick well and look natural. Exactly how much is sanded off depends on the type of veneer.
Conventional veneers
Classic veneers remove around 0.3 to 1 millimeter of tooth enamel. This corresponds to the thickness of the composite shells and prevents the tooth from appearing unnaturally thick after treatment. This conventional type is used when more extensive corrections of the tooth shape or color are required.
Non-prep or minimally prep veneers
The gentler version is so-called non-prep or minimal prep veneers, particularly thin veneers. Here, either no tooth enamel is removed at all or only a minimal removal of less than 0.3 millimeters is carried out.
These wafer-thin veneers can be applied directly to the tooth and are particularly suitable for you if you only need minor aesthetic adjustments and want to preserve your tooth structure as much as possible.
Contrary to the common assumption that non-prep or minimal prep veneers must be cheaper than conventional veneers, as they do not require sanding, they are usually even associated with slightly higher costs.
This is due to the fact that they must be manufactured extremely thin and at the same time precisely, which requires particularly precise work and high-quality materials.
