We are a mercury-free practice. However, many people still have silver/mercury fillings in their mouths from years past. Porcelain inlays and Tooth Colored Restorations (onlays) create fillings that are not only beautiful (or unnoticeable) but also add strength to weakened teeth. These restorations are esthetically pleasing and in many cases very strong thanks to new bonding technologies.
Disadvantages of Silver fillings:
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.
Advantages of Tooth-Colored Restorations
There are many advantages to tooth-colored restorations. For example, Resin onlays 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.
Since the resin used in tooth-colored restorations can contain fluoride this can help prevent decay. Tooth colored restorations are used as fillings.
Replacing Silver Fillings with a Tooth Colored Restoration
You can have your silver fillings replaced with tooth-colored restorations. Depending on the type of restoration, this process may require two appointments. This occurs when crowns, onlays or inlays are done. Routine tooth-colored fillings are done in one visit.
