Understanding Tooth Filling

A tooth filling is done to restore the shape of a tooth that has been ravaged by the process of decay. This helps one o regain the use of a tooth that had been misshapen. There are various fillings available in the market. They have different p44roperties that make them distinct. These are:

  • Color
  • Adhering properties
  • Longevity
  • Material
  • Cost

All these factors play a hand in which material a dentist can use for filling. Ceramic and gold fillings, for example, represent the top tier of fillings as they are the most expensive. Here is a breakdown of the different filling materials and their appropriate uses.

Gold Fillings

Gold fillings are the most durable filling available. They are also one of the most expensive. They are made of a gold alloy and are golden in color. This confines their use to fillings in the back of the mouth. Some patients may prefer to have their fillings to show as a status symbol and so may prefer them in the front teeth.

Ceramic Fillings

Made from porcelain, these fillings resemble the color of teeth. They are also highly resistant to staining from various elements like tobacco. The only downside to these fillings is they are brittle and can break. They ae also as expensive and at times more expensive than gold fillings.

Composite Fillings

Composite fillings are another filling with color similar to teeth. They are strong and bond directly to the teeth reducing the preparation done on teeth like drilling. The fillings are made from plastic and glass particles They are used on the front teeth and on visible parts.

Glass Ionomer Fillings

Glass ionomer is a composite of acrylic and a glass component, fluoro aluminosilicate. It is a highly durable filling used in severely decayed teeth. It is also used in baby teeth filling.

Amalgam Fillings

Amalgam fillings are made from a number of metals and are therefore not the color of teeth. Silver and mercury are some of the metals used. Amalgam makes for highly durable filling and is used to fill teeth at the back of the mouth.
