Why is it necessary to shave teeth for porcelain veneers?

Porcelain veneers require slight tooth reduction for a few key reasons. Shaving or trimming the teeth creates space for the veneer to sit flush with surrounding teeth, ensuring a natural look without adding bulk. This minor reshaping, usually 0.5 mm or less, allows the veneer to adhere securely and prevents it from feeling or appearing oversized. By removing a thin layer of enamel, dentists can also better bond the veneer, which improves its longevity and reduces the risk of detachment. Additionally, this process enhances the veneers’ fit and alignment, giving a smooth, comfortable result that complements the patient’s bite and smile.
