A filling helps restore a damaged tooth from decay. It brings the took back to its normal function and helps prevent further decay by eliminating areas where bacteria can enter. Your dentist will consider a number of factors when choosing which type of filling material is best for you.


Here are a few various types of fillings:

Composite Fillings – A composite resin filling is made from plastic and fine glass particles. Composite fillings are used most often on front teeth or the visible parts of the tooth. They bond directly to the tooth, reducing the amount of drilling needed. They are also much stronger than amalgam fillings.

Amalgam Fillings – Amalgam fillings are made from a mixture of metals including mercury and silver. It doesn’t match the color of your teeth. This type of filling is used most often for fillings in the back teeth which can’t be seen. These fillings are very strong and usually last at least ten years if not longer.

Gold Fillings – Gold fillings usually cost ten times more than amalgam fillings. They are made out of gold which is extremely durable. This type of filling lasts longer than any other type. Gold fillings also do not match the color of your teeth and are expensive.

Ceramic Fillings – Ceramic fillings are made of porcelain and match the color of your tooth.  They are much more brittle than composite fillings and can break. However, they are more resistant to staining.

Glass Ionomer – Glass Ionomer fillings are made from acrylic and fluoroaluminosilicate, a component of glass. It is sometimes used to fill baby teeth. It is also used in people who have lots of decay below the gum line.
