Tooth Fillings

Tooth colored fillings have replaced silver and gold fillings in our office.  It sounded funny 25 years ago to say that we no longer offered silver-mercury fillings. But, it also seemed strange that the amalgam material would come separately from all our other dental supplies. It came with a big red Hazardous Materials label on it. We are required by law to separate the old amalgam waste from our drain lines so that it does not contaminate the environment. So with all these precautions for shipping, handling and trashing how can it be 100% safe to use? We have been using ONLY tooth colored filling for over 20 years. The chemical composition of tooth colored fillings has evolved over the years. This material is made up of ceramic particles imbedded in a polymer matrix. The polymer matrix  polymerize when initiated by a bonding light. These tooth colored fillings are more wear resistant and polish better than materials used many years ago. The bonding agents we use have also evolved over time. The bonding agents we use today are manufactured to increase bond strength and reduce sensitivity as well. These bonding agents actually penetrate the tooth structure to bond INTO the dentin of the teeth and not just sitting on the tooth. These new generation bonding agents actually penetrate into the dentinal tubules of the teeth to chemically seal them. This has helped to greatly reduce the post operative discomfort experienced with the silver fillings we used 25 years ago. Of course patients also like the way the filling material blends in with the color of the natural teeth so no one can see that they have fillings in their teeth. The technique for placing these fillings is critical to a long lasting result. We take a lot of time and effort to carefully isolate the tooth being filled. We use the best materials on the market and we use the best filling shaping systems available so the fillings we do will best restore the natural shape and function to your teeth
