Hello, I had bonding done on a few teeth that were turning yellowish, I don't know if they were not polished correctly , but they are turning brown now. This was just done a few months ago, matched my teeth pretty well initially. Is it possible ny dentist used older type bonding ? If so , would A different bonding agent work much better? I am trying to avoid veneers, these teeth now look worse than when I started .
Answer: Discolored bonding Dear tommy140, There are a variety of different bonding materials and different polishing systems. I have used a microfill composite for cosmetic bonding for thirty years because it holds a fantastic long lasting polish. The newer nanohybrid composites are supposed to combine the durability of hybrid composites with the polishability of microfills. My experience is that they fall short when it comes to holding a polish, and I continue to use the old microfills with continued excellent results. The discoloration of your teeth is probably due to a roughened surface which is either due to a hybrid composite losing its initial polish or a polishing system that did not provide a glass like surface. That brown stain should be superficial and easily polished off. It is related to the type of material, it will return and then the only long term solution would be its replacement. However remember that no bonding material will last more than 3-10 years, but porcelain veneers will last indefinitely.
