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 design those silver fillings ultimately result in a weaker tooth structure. Newer tooth-colored composites create fillings that are not only beautiful and undetectable, but also add strength to weakened teeth. These restorations are esthetically pleasing and strong thanks to new bonding technologies.
Disadvantages of Silver fillings:
Silver fillings have many drawbacks. The edges of the silver filling can corrode, resulting in the tooth getting a new cavity. With age, the metal of a silver filling expands and contracts with high and low temperatures and can cause your tooth to crack.
Silver fillings contain 50 percent mercury, which is known to contribute to health problems. They can also stain your teeth and gums.
Fortunately, silver fillings can be safely replaced with tooth-colored restorations.
