A cavity is a hole in the tooth that can be caused by a number of factors. The causes of tooth decay can include your diet if it’s high in carbohydrates or sugary foods, gum disease, and aging. Some types of dental work can even cause cavities.
Fillings are used to restore teeth that have sustained damage. A filling is often used when someone has a cavity caused by tooth decay and might also be used in some other circumstances too. If you damage your tooth for another reason, such as in an accident, a filling might help to fill a gap.
If you need to have a filling, one of the most important things to consider is which material to use. Fillings have existed for many years, and in that time a range of different materials have been used for them.
Metal amalgam fillings have been in use for more than a century. They are durable and affordable and have been tested more than any other material.
Other types of filling include ionomers, porcelain fillings, porcelain-fused-to-metal, gold or base metal alloys, indirect composites, and bondings. All of these filling types offer different advantages and disadvantages for different purposes.
