White fillings do have some advantages over amalgam. Amalgam fillings require some preparation, which affects the healthy portion of a tooth.
As time progresses, silver fillings loosen and create tiny air pockets, which causes bacteria to build up and can lead to tooth decay. By using the holistic solution of composite white fillings, this situation can be avoided.
In addition to the avoidance of potential health issues caused by loose silver fillings, white fillings resemble the colour and texture of a natural tooth and are, therefore, more discreet and aesthetically pleasing.
