Many patients choose to replace their old mercury or metal fillings with tooth-coloured composite ones for a few reasons:
Composite Fillings Withstand Temperature Changes
Metal (or amalgam) fillings are made with a mix of metals, including mercury, which can expand and contract with temperature changes, like when you drink hot coffee or eat ice cream. Over time, this constant shifting can lead to tiny cracks in your teeth, weakening the tooth structure and increasing the risk of breaks or further decay. On the other hand, composite fillings do not change with temperature.
Composite Fillings Are Colour-Matched to Your Teeth
Another reason patients prefer to replace metal fillings is aesthetics. Metal fillings are noticeable and can darken over time, whereas mercury-free composite fillings blend seamlessly with your natural tooth colour for a much more discreet, attractive look.
Composite Fillings Do Not Contain Metal or Mercury
Finally, many people feel more comfortable with mercury-free fillings due to health concerns around mercury exposure. While research is ongoing, mercury-free composite fillings are a popular choice for those seeking a safe, metal-free alternative that looks great and also helps protect their natural tooth structure and strength.
