For over 150 years, cavities were filled with a mixture of metals, including silver and mercury. It was perfectly normal to see dark grey areas in someone’s mouth when they laughed.
But today, you can get your cavities, as well as any other small, hollow area, in your teeth, filled with a natural looking composite resin or tooth colored filling. Composite resins are made from a durable mixture of plastic and glass similar in color to natural teeth. This makes the treated tooth less noticeable compared to other types of fillings. Composite resins can be used for filling cavities, as well as correcting the size, color, and shape of teeth. They can be used on the front as well as back teeth.
There are several other advantages to using composite resins. They are compatible with sealants, which allow the dentist the option of performing both procedures in a single visit, preventing further decay. Another benefit is the ability of composite resins to form a strong bond to tooth structure. This decreases the chance of further tooth decay by providing a tight seal on the affected area. In many situations, composite resins can be repaired by simply adding more composite material.
