What is the recommended reduction depth for a veneer?

A veneer is a thin layer of material, typically ceramic or composite resin, that is applied to the facial surface of a tooth. The recommended reduction depth for preparing a tooth for a veneer is generally around 0.5 mm. This minimal reduction is ideal as it preserves as much of the tooth structure as possible while still allowing enough space for the veneer to be successfully bonded to the tooth surface.

Maintaining a conservative reduction helps in achieving aesthetic results and ensuring the longevity of the veneer, while also minimizing risk to the underlying tooth. Adequate thickness allows for proper light transmission and esthetics, ensuring that the veneer matches the natural appearance of the surrounding teeth.

In contrast, greater reduction depths, such as 1.5 mm or 2.0 mm, would compromise tooth structure unnecessarily and could lead to complications such as increased sensitivity or a higher likelihood of needing additional restorative work in the future. Therefore, 0.5 mm is the appropriate choice for veneer preparation, balancing aesthetic outcomes with tooth preservation.
