Many people still have silver/mercury (Amalgam) fillings in their mouth from old dental work; we can replace them for you. Aside from the cosmetic improvement of having a tooth coloured filling that is much more aesthetically pleasing and very strong, there are notable advantages to replacing the silver-coloured fillings in your mouth.
Disadvantages of old silver-coloured Amalgam fillings
Amalgam fillings have many drawbacks.
- The silver/ mercury fillings are unattractive and can actually result in a weaker tooth structure.
- The edges of the silver filling can wear down, become weak or break. This results in the tooth not being protected and allows cavities to start once more.
- With age, the metal of a silver filling expands, contracts, and can split. Usually it is part of your tooth itself that will crack or break off, ultimately leading to a
- larger filling, crown and even root canal treatment.
- Silver fillings contain 50 percent mercury. They can corrode, leak and cause stains on your teeth and gums.
How Large are your Fillings?
Depending on the size of your amalgam fillings, we can replace it in a variety of ways. If the filling is small and the tooth needs a direct restoration, we’ll replace the amalgam filling with a tooth-coloured one. This can be done in one appointment. If your filling is larger, we recommend something called an indirect restoration. This is when your amalgam filling is replaced using a very strong tooth-coloured dental inlay or onlay.
The indirect restorations are made of gold, porcelain or a processed composite resin. Depending on where in your mouth the restoration will be, you can choose whichever material you wish. The process of doing an indirect restoration takes two appointments.
