What are the advantages of having a tooth-colored filling over a silver filling?
First let us say a very big thank you to all of the teachers in the world and happy Teacher’s Day!
I teach through many mediums- whether it is within the walls of my practice, at New York University’s College of Dentistry, or while lecturing at North Shore University Hospital. I have been utilizing this blog to answer the questions we most frequently receive and it is an extension of my enjoyment to be involved in education.
One question that I frequently receive is in regards to composites (tooth-colored fillings) and what the advantages of a tooth-colored filling are over a silver (amalgam) filling.
The composite resin fillings have come a long way in recent years. Their strength and longevity are now comparable to that of silver fillings, but with much-enhanced esthetics. The dentist has the capability to match the filling shade exactly to the shade and color of your tooth so that no one else will ever know you had a cavity. Another advantage of these tooth-colored restorations is that the preparation is relatively conservative. Only decay is removed, and the filling is then bonded to the area that has been prepared. Silver fillings do not have the same bonding capacity, and therefore rely on on mechanical retention to hold the filling in place. As a result, good tooth structure is taken away create the ideal depth and undercuts required to achieve adequate retention. another advantage of composite restorations if that they are typically less sensitive to hot or cold, as metal tends to conduct temperature more readily.
Tooth-colored restorations are yet another great reason to smile.
I welcome any questions you may have and again, I hope all of the teacher’s of the world have a great day and know you are celebrated.
