When preparing tetracycline stained teeth for veneers, which consideration is NOT generally taken into account?

When preparing tetracycline-stained teeth for veneers, the primary focus is on addressing the aesthetics of the teeth while preserving as much healthy tooth structure as possible. One important consideration is that not all discolored enamel needs to be completely removed. This is because excessive removal can lead to tooth sensitivity, compromise the structure of the tooth, and leave the tooth more vulnerable to future issues. It is typically sufficient to prepare the teeth in a way that allows the veneer to cover the stained surface effectively, using materials and techniques that can mask or modify the discoloration without the need for complete removal of the stained enamel.

Vital bleaching is often suggested prior to veneer preparation to lighten the underlying shade and enhance the final outcome. Color modifiers can also be utilized in the veneer process to effectively conceal any remaining discoloration after the tooth preparation. Additionally, ensuring proximal extensions are into the contact area helps maintain proper fit and esthetic alignment. Therefore, the notion that all discolored enamel must be completely removed is not a standard consideration in this context, as conservative treatment is preferred.
