If a cavity is detected during a check-up, your dentist can provide a dental filling before it develops into a more serious problem. Dental fillings replace part of a tooth that has been lost because of decay, wear or accidental damage.
What is a filling made of?
Typically fillings are made from either amalgam (silver fillings) or composite (white/tooth coloured fillings).
Amalgam fillings are made out of mercury mixed with silver, tin, zinc and copper. They are commonly used on back teeth as they can withstand the strong forces of chewing. These fillings are the least expensive type of restoration.
White fillings are made of synthetic resin materials (composite). There are also materials that contain glass particles (glass ionomer). These fillings can be used to restore decayed teeth and to improve the shape/colour of disfigured, malformed and chipped teeth. Minimal tooth preparation is required and once placed they can be used immediately.
They are more aesthetically pleasing since they match your natural tooth colour and appearance.
Frequently Asked Questions
Data shows that fillings can last for more than 5 years. We are confident of the quality of our fillings so we guarantee them for 1 year.
Yes, though we generally recommend that fillings of any kind be replaced only when clinically necessary, for example; if decay occurs or when fillings break. Sometimes, when the existing fillings are very large, a composite filling may not be an option – a porcelain inlay may be required.
Many patients prefer tooth coloured fillings because they look natural and cannot be seen when you laugh or smile.
