What are Dental Fillings Made of?

Happy patient

If the dentist has found a cavity in your tooth, then he or she will remove the decay and restore your tooth with a dental filling. Dental fillings can be made of several different types of materials.

Silver amalgam is one of the materials that can be used to make a dental filling. This type of filling consists of mercury that has been mixed with silver, tin, zinc, and copper. This type of filling dates back to the nineteenth century. It is quite durable and generally the cheapest type of filling, but it is also the least cosmetically pleasing. Gold is also used in fillings and can be dated back to around the same time as silver amalgam. Gold is very strong, but it is also quite expensive and takes two visits to the dentist in order to place it. Composite resin fillings are tooth-colored and therefore are the most cosmetically pleasing option available. Composite resin is a mixture of plastic and fine glass particles. Composite resin fillings are the same material that is used in dental bonding.
