At some point or other in ours lives, most of us wind up with a cavity. In most cases, a cavity calls for your dentist to remove the decay and to fill in the tooth area that was removed. There are two basic types of fillings used:
Most of us have had amalgam fillings (silver) or gold filling restorations. Some amalgam fillings were what we have called mercury fillings, as some amalgam fillings contained mercury. Metal fillings were effective, but very conspicuous and tended to blacken in color over time. Their safety has been in question for a number of years due to concerns over the absorption of elemental mercury contributing to several diseases, including Alzheimer's, multiple sclerosis, dementia and arthritis.
Composite resin dental fillings were created as an alternative to traditional metal dental fillings.Tooth fillings colored to look like a natural tooth are known as Composite Resin Dental Fillings,are made of a plastic dental resin. There are no known health risks of receiving composite fillings. Composite Resin Dental Fillings are strong, durable, and make for a very natural looking smile. Composite resins is used as a tooth bonding procedure, the resin will strengthen and enhance the natural tooth structure as it does with use as a dental filling.
Mercury fillings or amalgam fillings can easily be removed and replaced with far more attractive colored fillings. These fillings actually strengthen your tooth beyond the level it had with the amalgam fillings.
