Tooth Color (Composite) Filling vs Silver (Amalgam) Filling

Composite and amalgam fillings are the two most widely used filling materials. Composite resin is made of tooth Color filling while silver filling is made of mainly silver and mercury. Even though there is no scientific evidence to prove that the mercury in silver filling can cause harm in human body, it will nonetheless cause detrimental effects to our environment. That is why the state requires each dental office to implement amalgam collectors to make sure it is disposed of properly. Beside the environmental consideration and though it is relatively inexpensive and easy to handle, there are also other factors which prevent our office from using amalgam fillings. The reasons we only use composite fillings besides the above mentioned factors are: it is much more esthetic, it can bond to the tooth structure so we can minimize tooth drilling (amalgam filling relies on physical design to lock it in place so we often have to drill beyond the extent of the decayed tooth structure and often further weakens the tooth structure), and when combined with a glassionomer, composite filling can release fluoride to promote remineralization of the tooth structure.
