Fillings are used to replace a portion of your tooth which has been lost either due to dental decay or damage. Amalgam is a metal alloy made up from various metals which when mixed can be placed into a tooth and which subsequently hardens restoring the tooth's original shape and function. The amalgam alloys which we use at Malden Dental Care are modern alloys which have extremely high strength and high corrosion resistance. They do play an important role in providing strong stable fillings in back teeth for those patients who wish to have them once all the options have been discussed.
