Many people still have amalgam/silver fillings in their mouths from years past. These fillings are not particularly pleasing to the eye, and we know that by unavoidable design, these fillings ultimately result in a weaker tooth structure. 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 very strong thanks to new bonding technologies.
Disadvantages of Silver fillings:
Silver fillings have many drawbacks, although they may last for a very long time 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 fractures of the filling as well as, the surrounding tooth structure.
Advantages of Tooth-Colored Restorations
There are many advantages to tooth-colored restorations. 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. Resin wears like natural teeth and does not require placement at the gum line, which is healthier for your gums!
