Traditionally, tooth cavities were restored using amalgam or gold. These two materials were readily available and durable. Eventually, new non-metallic materials called composite resins were developed and largely replaced the metal-based fillers. In addition to performing well (being strong and durable), composite resins are aesthetically pleasing, blending well with the natural tooth colour. Their basic white colouring can be tinted to perfectly match the person’s tooth enamel, making the filling(s) virtually invisible. Given the advantages of “white fillings”, many patients decide to use them not only for their new restorations but also gradually use them to replace their old amalgam fillings at dental centre Clarence.
