Dental amalgam or silver  fillings  have been used for over 150 years.  A good question is Why? Most people wouldn’t be happy  using a treatment that was century old technology for any other healthcare need so why would we accept this for our smiles?

Amalgam fillings were originally created as a low cost alternative to gold fillings – the only filling material available at the time.  The original recipe contained silver shavings, zinc, copper, tin and mercury.  Back then people didn’t understand that mercury is a powerful neurotoxin. We know better now.  This controversial substance is still  used by some dentists because of its low cost and because it is quick and easy for dentists to use. This is not a good standard for health care decisions.

There are other risks to these old fashioned  fillings as well.  The amalgam material is very sensitive to temperature changes – it expands and contracts in the presence of heat and cold.  This often causes small cracks and fractures in the filling which can cause tooth sensitivity or even weakening of the tooth.  The tiny cracks can also allow bacteria to enter through the filling leading to additional decay and creating a bigger problem in the future.  The black colored fillings are also  very unattractive and cause dark shadows on an otherwise pretty smile.

Dentistry today offers many different types of composite filling materials that are bonded to your tooth structure.  These composites protect against future decay and help strengthen the tooth once they are bonded into place.  A composite filling won’t change shape or be affected by what you eat or drink.  Best of all, because these fillings are matched to your natural tooth color, they are virtually invisible when you smile.
