Composite (white) fillings are made from natural tooth coloured resins which aesthetically pleasing and can be matched to the same colour as your natural teeth.
Amalgam (silver) fillings are made from an amalgamation of different metals and are silver in appearance. Amalgam fillings are resistant to wear, although due to their colour, they are more noticeable than composite fillings. As such, they tend not used in very visible areas, such as the front teeth. We use amalgam rarely, but in certain situations in the back teeth, it can serve as excellent material with durability.
