A composite filling (white filling) repairs the part of the tooth damaged by decay, fracture or abnormal wear, while resolidifying the tooth. Any decay left untreated in early stages will worsen and other treatments could potentially be necessary. 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 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.
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 let 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. Fortunately, silver fillings can safely be replaced with 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. Since the resin used in tooth-colored restorations contain fluoride this can help prevent decay. The resin wears like natural teeth and does not require placement at the gum line, which is healthier for your gums!
