The most obvious advantage of non-metal fillings is that they blend in with your teeth more than silver amalgam fillings.
Amalgam fillings can also corrode over time and may discolor the area where the filling meets the tooth. Don't be fooled by name and color: silver amalgams are made up of more than just silver. "Amalgam" means a mixture or blend - silver amalgam fillings are a mix of silver, tin, zinc, copper, and mercury. That last ingredient should alarm you because silver amalgam fillings are indeed about 50% mercury. Most oral health experts believe that this small amount of mercury is harmless but there are others who are concerned about the possible long-term effects.
Traditional silver amalgam fillings do not easily bond to teeth. To ensure that the fillings fit snugly and adhere to teeth, dentists prepare a pocket by drilling extra and removing some healthy tooth structure.
In addition, when you have a silver amalgam filling sitting near a gold filling, the two metals interact and your saliva can produce an uncomfortable electric current known as galvanic shock.Make an Appointment at Deldar Dental
