Old Vs New

Which FILLING is best for you?

When it comes to your dental health, there is a lot of information available online for you to read.  We want to help explain two different types of fillings.

Amalgam (Metal) Fillings:

  • Amalgam fillings are made from a mixture of metals giving it the silver appearance.

  • This type of filling is used mostly for back teeth.

  • Amalgam fillings are strong and long lasting, ranging on average 10 - 15 years.

  • Amalgam fillings do not bond directly with the tooth thus, the filling needs to be made large enough and deep enough for the material to sit securely within the tooth. Therefore, healthy tooth structure may also need to be taken away.

    • These fillings can cause a lot of pressure on the teeth and may therefore cause cracks and fractures within the natural tooth structure.

  • As long as an amalgam filling is in good condition there is no medical need for it to be replaced, unless for aesthetic reasons.

Composite (white) fillings:

    • A composite filling is made of a range of plastic tooth-coloured materials. The material allows us to closely match the filling to the tooth colour.

  • Composite fillings bond directly to the teeth, therefore reducing the need to remove healthy tooth structure.

  • These fillings set immediately and therefore are safe to eat on straight after your appointment.

    • This type of filling can be used for both front and back teeth and can last on average of 7 years. 

While there is no immediate need to replace metal fillings with white fillings, you and your dentist can decide the best timing for you. If you have any questions about your fillings ask our dentists the next time you visit.
