We have all seen the metallic silver style fillings in our parent's teeth and in some cases even in our own mouths, silver amalgam fillings are a mixture of liquid elemental mercury and a fine powder consisting of Iron, Zinc, Magnesium, Copper and some other rare earth metals. The primary deficiency in these silver fillings is that for the most part they are not bonded to the natural tooth structure. Hence they can full out when a part of tooth fractures away as the result of dental decay or through accidental traumatic biting on something too hard or both.

​

Dentists have moved away from these types of fillings for a number of reasons. Aesthetically that is appearance, is very unattractive to a person’s smile. They also can result in low-level leaching of mercury in the metal alloy that is the silver filling… into the owner's oral fluids and then swallowed and goes into the stomach lining and finally into the bloodstream.

​

Any patient who wishes to remove and replace these silver fillings must ask his/her dentist to do that with the composite resin that we have today.

​

Now simple replacement with the composite resins that we have today requires a new type of tooth preparation to receive and survive for a significant term (3 to 5 years). There are many steps that must be completed in order to achieve a successful  performance of what the public calls “white fillings.” The final choice of the right shade, the preparation of the tooth to receive the composite resin filling, the check of the bite, and the final high gloss shine can result in a very magnificent tooth restoration.
