Where teeth are not properly cleaned, bacteria creates a film called plaque. Plaque produces acid which eats enamel and eventually causes cavity. To stop cavity penetrating interior part of your tooth, dental fillings treatment is performed. Dental Filling treatment restores function and integrity of teeth by filling is with restorative material.

Amalgam Fillings

Amalgam Fillings (Silver Fillings) are used for many decades for dental filling treatment. Nowadays amalgam fillings are becoming less popular because their color don't match with teeth and do not look natural. Amalgam Fillings which are popularly known as metal fillings are made with mixture of silver and other metals like copper or 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 vapour is toxic but mercury molecules in hardened amalgam are bound to the silver molecules rendering the level of toxicity harmless.
