Modbury Dental – Replacing mercury fillings with white fillings
Can you believe that those silver-coloured fillings called ‘amalgam’ have been around since 1812? They were created by a British chemist, Joseph Bell, over 200 years ago! Amalgam is a specific mixture of metals, consisting of liquid mercury and a powdered alloy of silver, tin and copper. They bind together to form a putty allowing for placement into dental cavities. Once placed, it quickly sets to form a strong filling.
Nowadays, many patients request to have their old mercury fillings replaced with white fillings, mainly for aesthetic reasons or fracture, but sometimes for perceived health reasons. Although we no longer place amalgams routinely at Tea Tree Dental, this is primarily due to aesthetic or tooth-integrity concerns.
