We are a moving towards a mercury-free practice. However, many people still have silver/mercury fillings in their mouths from years past. We know that by unavoidable design, silver/mercury fillings ultimately result in a weaker tooth structure. In addition, these fillings are not particularly pleasing to the eye. Composites (tooth-colored restorations) create fillings that are not only beautiful (or unnoticeable) but also add strength to weakened teeth. These restorations are aesthetically pleasing and very strong thanks to new bonding technologies.
Disadvantages of Silver fillings:
Silver fillings have many drawbacks. The edges of the silver filling can wear down, become weak or break. This results in the tooth not being protected and lets cavities get started once again. With age, the metal of a silver filling expands, contracts, and can split the tooth.
Silver fillings contain 50 percent mercury. They can corrode, leak and cause stains on your teeth and gums.
Silver fillings can be safely replaced with composites (tooth-colored restorations).
Advantages of Tooth-Colored Restorations
There are many advantages to composites (tooth-colored restorations). They are bonded to the teeth creating a tight, superior fit to the natural tooth. Such restorations can be used in instances where much of the tooth structure has been lost. The tooth remains intact and stronger.
We also use adhesives in conjunction with composites that contain fluoride, which can help prevent decay.
The result is a beautiful and healthy smile!
