It is always important to remember that all fillings have their own strengths and weaknesses.
With advances in technology, white fillings now last many years and present many advantages over traditional amalgam fillings:
- Porcelain and composite resin fillings are able to be very closely matched to the colour of our teeth, meaning that we can get a perfect aesthetic outcome with them.
- Tooth coloured fillings do not contain any mercury. While there is no conclusive evidence of the harmful effects of amalgam fillings on our body, we respect that a lot of patients do not want any mercury in their teeth. Tooth coloured fillings present a viable alternative.
- Tooth coloured fillings are not affected by temperature. Therefore, hot and cold food/drinks do not have any impact on them
While amalgam fillings are very strong, they have a number of drawbacks:
- In the long term, amalgam fillings can actually weaken our teeth. This is because they expand and contract according to the temperature of the food and drinks we consume. This places a lot of stress on the teeth that are holding the fillings in and increases the risk of the teeth breaking over time.
- Amalgam fillings are dark and will stain the teeth over a period of time, meaning that those teeth may not be aesthetically acceptable.
- Amalgam fillings contain mercury, which can be an issue for a lot of patients due to the potential toxic effects of mercury in our body (this has not been conclusively proven) and also its impact on our environment.
Porcelain fillings are much stronger than composite resin fillings and will generally last much longer.
