Why We Recommend Tooth-Colored Fillings
Why Should You Replace Your Silver Mercury Fillings?
Mercury fillings were used for many years in dentistry. You’ve likely had one in your lifetime. In recent years there has been a shift away from mercury for several reasons. Dr. Vantramp and Dr. Zingerman recommend replacing mercury fillings with porcelain tooth-colored fillings because they result in a stronger tooth and higher aesthetic value.
The Disadvantages of Silver Fillings
The edges of silver fillings tend to wear down over time. Eventually, they become weak and break, which results the tooth not being protected. When this happens the tooth is at risk of cavities. Also, silver fillings will tend to expand and contract, which can cause the tooth to split. Again this results in bacteria and possibly cavities. Silver fillings also contain approximately 50% mercury. Mercury can corrode leak and potentially cause stains on your teeth and gums.
The Advantages of Tooth-Colored Fillings
Resin Onlays are bonded to the tooth creating an extremely tight fit, which is superior silver fillings. We always want to save as much of the tooth as possible. Restorations using resin can be used in a situation when most of the original tooth has been lost. This allows the tooth to stay intact.
Also, the resin used in tooth-colored restorations contains fluoride, the tooth helps to fight off decay. The resin also wears like a natural tooth and does not require placement at the gum line. This results in a wonderfully natural-looking smile.
