If a single spot on one of your teeth is not cleaned daily, the remaining bacteria will transform themselves into a sticky film substance called plaque. The plaque will produce acids which eat away at the enamel of the tooth and will eventually cause cavities. When the cavity gets through the enamel, into the underlying tooth structure (the dentin), repair or restoration is necessary.
Traditional Amalgam FillingsAmalgam (silver) fillings have been used for decades and they remain one of the most commonly used filling materials. They are often referred to as metal fillings. Amalgam is a mixture of silver and other metals, such as copper, tin and zinc, grounded into powdered form. The silver powder is mixed with mercury and placed into the cavity preparation where it is shaped before hardening.
In recent years, the safety of amalgam fillings has come under scrutiny because of the mercury it contains. The absorption of elemental mercury is known to be a contributing factor to several diseases, including Alzheimer's, multiple sclerosis, dementia and arthritis. However, recent studies have proved amalgam fillings to be perfectly safe. It is true, that mercury vapor is toxic but mercury molecules in hardened amalgam are bound to the silver molecules rendering the level of toxicity harmless. The American Dental Association and the Food and Drug Administration have researched the safety of amalgam fillings and have found them to be not only safe but extremely effective.
Tooth Color Composite FillingComposite 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 and are made of a plastic dental resin combined with porcelain and glass particles. These types of fillings are, durable and are way more natural looking than amalgam fillings.
If you have a cavity in a tooth or broken fillings or if your teeth are full of mercury fillings, or amalgam fillings you may want to ask your dentist about changing to composite dental fillings . Mercury fillings or amalgam fillings can easily be removed and replaced with far more attractive colored fillings. Research shows that composite fillings actually strengthen your tooth and further protect it from decay. For more information please visit filling replacement page.
