The greatest challenge in aesthetics arises when one or two anterior teeth are involved, as achieving a perfect match in color and shape with the existing dentition is extremely difficult for the new crown or veneer.
To address this, one common option is to involve several healthy teeth with veneers or crowns, potentially converting a single-tooth issue into multiple possible future problems. The other option, and the most difficult one, is to confine the issue to the affected tooth while achieving an excellent outcome and preserving natural aesthetics.
