Hello, Based on the photo that is displayed, it appears that there was one porcelain veneer placed on your upper left lateral incisor. It is difficult to determine whether or not a porcelain veneer was your best option since we have no picture of what the tooth looked when it was chipped. I could understand why you are not satisfied with the aesthetic outcome of your treatment. In order to correct this issue, we need to identify the problem first and come up with a solution that will satisfy your needs. In my opinion, this tooth is shaped too much like a rectangular where as your upper right lateral incisor has a more triangular shaped. What I would do to replace this is take moulds of your existing teeth and explain to the master ceramist (the lab technician that makes your teeth) the desired shape which would be to match the right lateral incisor. Next, our master ceramist would fabricate a diagnostic wax up of the new shaped tooth on your models.. You would then come back for your initial visit of treatment and remove the existing porcelain veneer. Based on the diagnostic wax up, we will be able to determine if there was sufficient enamel reduction of your tooth. In other words, your existing veneer could appear too "bulky' because maybe there was not enough enamel reduction. In that case, we would have a guide from our wax up to determine exactly how much tooth we would need to remove. Typically, we can make the porcelain veneers as thin as 0.3-0.5 mm. Once we have sufficient reduction and have a clean preparation of the tooth, we would make a final impression for the ceramist to make the new veneer off. Finally, and here is the best part, we would fabricate a provisional based on the new shape of the tooth. At this time, you will be able to assess the aesthetics of the provisional. Modifications can be made until you are completely satisfied with the aesthetic outcome. Once completely satisfied, our master ceramist will fabricate the new porcelain veneer based on your provisional. The last tricky part is matching the shade to the rest of your teeth. I would recommend that a custom shade be performed by the cosmetic dentist and lab ceramist during the initial visit. In addition, it is imperative that they take a stump shade, which is the shade of the underlying prepared tooth in order to match the shade properly. Once you find the right dentist who works with the right lab ceramist, you should have no issues getting the result you desire. I wish the best of luck to you and please do not hesitate to ask any further questions.
