Mercury free fillings are what we will use on your teeth at our practice. The most advisable one is Resin – Composite fillings. They are more appealing due to their nature of easily blending with the natural coloring of teeth. Moreover, composites require less removal of teeth structure since they bond to the tooth. Therefore, they restore most of the original strength of the tooth. Amalgam fillings were used by dentists before and by weight it contains 50% mercury, joined with silver, copper and tin.
