Dental Fillings Framingham MA

We use various material to fill teeth. In general there are two category filling material: Amalgam (known as silver/mercury fillings) and Resin (known as composite or white fillings). They both have their advantages and disadvantages. For more information, we encourage you to visit the ADA website or the FDA website. These are the best sources that will help you to understand the difference between these two materials. You may also call our office: Framingham Office Phone Number (508) 270-6770.

Silver Fillings

Amalgam has a long history of almost 150 years of usage, and research that supports it. It has its indications. It is used mainly for posterior teeth.

Dental amalgam fillings are strong and long lasting; they are least expensive type of filling material. Approximately half of a dental amalgam filling is liquid mercury and the other half is a powder alloy of copper, silver, and tin. Mercury is used to bind the alloy particles together into a strong, durable, and solid filling. The new alloy called amalgam contains elemental mercury, but it does not contain any toxic form of methylmercury, which you may find in fish or other sources; thus amalgam is not toxic. For more information ask Dr. Maddahi or Dr. Singh to help you to understand better.

White Fillings

Resins have been around for may be 50 years, less than half as long as amalgam. They have their indications. They are great material for restorations of anterior teeth and posterior teeth.

In Addition to the above material, 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.
