The two most common materials to repair a cavity are dental amalgam and composite. Both materials do an excellent job of repairing cavities, but there are some differences to consider when choosing your restoration.
Dental amalgam, or silver filling, is made of a mixture of metals and is most commonly used to repair cavities in the back of the mouth. It is extremely durable and has been used for fillings for many years.
However, dental amalgam does not mimic the tooth’s natural color, and does not bond to tooth material.
Over time, this can result in the tooth developing cracks and the filling falling out. It is also more likely to be heat- and cold-sensitive.
With a composite filling, the shade of the material closely blends with your natural tooth color. It is physically bonded to the tooth, is highly durable and visually appealing.
