Fillings are the most common type of ‘restorative treatment’. A filling replaces the part of the tooth that has been lost because decay has caused a cavity in the tooth or because the tooth has broken. One option in restoring the tooth is to have a white filling, commonly known as a ‘Composite Filling'.
Second option being grey metal called ‘Amalgam’. Amalgam – Sometimes referred to as a silver filling. This is an alloy which is made up using Mercury, Silver, Tin, Copper and Zinc.
- It is extremely durable and able to withstand the grinding and chewing of the molar teeth over long periods of time.
- They are less expensive than white fillings
Fillings do not just have to be practical, they can also be aesthetically pleasing and thus many patients no longer have the desire for amalgam fillings because they are visible : with most white fillings, no-one would know it was there.
Composites can be used for a variety of cosmetic dental procedures
- Repairing chipped or broken teeth
- Closing gaps between your teeth (diastemas)
- Reshaping your teeth
Composite is not ideal for all restorations on back teeth especially if you have a large cavity, as bonding does not have the strength over large areas or if you have a heavy bite, grind or clench your teeth. The alternative tooth coloured restoration then would be an inlay or onlay.
