Dental Fillings in Indianapolis IN
We are a mercury-free practice. However, many people still have silver/mercury fillings in their mouths from years past. These fillings are not particularly pleasing to the eye, and we know that by unavoidable design, silver/mercury fillings ultimately result in a weaker tooth structure. Porcelain inlays and tooth-colored fillings (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
Fortunately, silver fillings can safely be replaced with tooth-colored restorations.
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.
Silver fillings contain 50 percent mercury. They can corrode, leak and cause stains on your teeth and gums.
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 diseased or lost while allowing the tooth to remain intact.
Since the resin used in tooth-colored restorations chemically bonds to the teeth this can help prevent decay. The resin is metal-free which will prevent instances of metal sensitivity and the darkening of teeth. The resin wears like natural teeth and the result is a beautiful smile.
