In addition to the clear aesthetic advantage that metal-free tooth-colored fillings offer, these fillings have even more advantages:
Like any other metal, amalgam fillings contract and expand when exposed to hot or cold temperatures. This means that any time you indulge in a piping hot cup of tea or enjoy a frozen treat in the summertime, all your metal fillings move slightly. Over time, these minute movements make the area more susceptible to decay. They may also cause cracks and other damage to your tooth.
Tooth-colored fillings also require less removal of your natural tooth surface during placement than metal fillings. We believe in providing the most conservative treatment possible in almost every situation, and composite fillings help us to do this.
