Can Permanent Existing Crowns Be Matched?

You can match veneers to crowns but you should first evaluate the cosmetics of the existing crowns.  Sometimes it is more ideal to redo the front four if you are not totally pleased with the color or shape of existing crowns.  In my office I use a botique dental lab for anterior crowns and veneers and they will come to my office when we deliver a case to custom stain veneers and/or crowns.  This is especially useful matching a patients natural teeth when only one or two teeth are being done. 

 

Wanting to match old crowns with new crowns can be done with the right ceramist.   However, what we have found that often the original crowns will dictate not only color,but shape and position of the teeth which for a cosmetic smile may not always be ideal.  So we often try to have the patient evaluate their entire smile before we try to match older crowns with possibly older materials and poorer esthetics compared to today's materials and techniques.  Long term you are better starting fresh with all new teeth at the same time it allows the size shape and color of your new smile be idealized 

Am I understanding correctly that you are happy with your crowns on your front two teeth?  Are they all porcelain crowns or porcelain fused to metal crowns.

If they are porcelain fused to metal crowns, then veneers placed on the adjacent teeth that have the old bonding will probably not match exactly.  Reason:  light goes through veneers and natural teeth much differently that porcelain fused to metal crowns.  However, they can certainly be done to better match the front two teeth than the composite bonding that continually darkens and needs replacement every few years.

My observation is that to get the best permanent match you might consider having the four front teeth all redone at the same time with the same type of porcelain.  The front two teeth (central incisors) could have all ceramic crowns and the teeth next to them (the lateral incisors) could have porcelain veneers.  Then everything should match well, and using the more modern techniques and materials, your restorations should give you years and years of service.
