Patients’ desires to have beautiful, white teeth is widespread in our culture, and dentists routinely use procedures such as bleaching, bonding, veneers, and crowns to provide patients with the smiles they desire. When a patient presents who requires or desires restoration of multiple anterior teeth for structural or esthetic reasons, the usual decisions facing clinicians involve tooth preparation design, what porcelain to use, and the final position, form, and color of the restoration.1
Now the dentist is faced with a new challenging decision: either restore only the problem teeth, attempting to match the bleached natural teeth that the patient likes, which can be very difficult; or restore all of the teeth, which is much easier and more profitable for the dentist, but which involves restoring teeth that don’t need any treatment simply for the sake of convenient shade matching. There is no easy answer to this dilemma. If the patient’s natural teeth are poorly shaped, worn, have large restorations, or some other condition for which they may benefit from restoration, then restoring all of the teeth makes sense.2 It’s when the natural teeth don’t need any treatment that restoring them—simply to match the shade of a problem tooth that is being restored—must be carefully examined. The pros and cons of restoring multiple teeth, versus getting one to match, must be presented to the patient.
My approach has always been to tell patients that if the natural teeth are acceptable—to the extent that the only reason to treat them is to match the color of the restoration being placed on another anterior tooth—then they are usually better off doing what is necessary to match the single restoration to the acceptable natural teeth3 (Figure 2). I also explain that matching a single anterior tooth is one of the most difficult things I do, and that less than 50% of the time does the first restoration match perfectly.4 I may need to make 2 or 3 restorations to achieve an ideal match and, because of this, the fee to treat a single anterior tooth is variable. Depending upon how many times it must be remade, it could cost as much as having 2 or 3 teeth done in order to make it ideal (Figure 3).
This difficulty is obviously magnified when treating maxillary central incisors. Getting laterals or canines to match acceptably is a much easier proposition. I also inform the patient that because the natural teeth are in good condition and esthetically acceptable, the most predictable long-term prognosis would be not to treat them.5
It is ultimately the dentist’s judgment and patient’s desires that determine whether it is better to proceed with restoring multiple teeth or just the isolated problem teeth. How adamant the patient is about what he or she wants, the competency of your dental laboratory, and your ability to communicate with the patient and the technician will ultimately influence your decision. In the end, as in many areas of dentistry, there is not one right answer.
