Silver vs. White Fillings: What’s the Difference?

Cavities are a frequent problem people routinely go to the dentist for.   If it is not a severe case, the dentist often will take out the decayed part of the tooth and place a filling to patch it up.  There are two commonly used fillings that the dentist used.  Amalgams are usually referred to as silver fillings. Composite resin on the other hand is popularly known as the white fillings.

The silver amalgam has been used in dentistry for over 100 years.  It is usually made of mercury and silver as well as small amounts of tin, nickel and copper. They are mixed in different percentages to form the silver alloy filling. Quite a few dentists prefer this type of material especially when working on the molars because it is very durable and lasts for 10 to 15 years.  A negative aspect to the silver amalgam is the look.  The silver color doesn’t blend with the color of your teeth. Another thing to think about before choosing the silver filling is the mercury content.  Since the silver filling contains about 50% mercury there is a possibility of it leeching into the body.

Composite resin on the other hand is the more natural looking filling that can blend with your teeth.  Nowadays the color of the filling can sometimes match the exact shade of your teeth. They’re perfect to use in the front teeth or any of the visible parts.  They are mainly made of acrylic and glass particles.  One thing that makes people choose them over silver fillings is that they contain no mercury.  One concern however about white filling is the lack of durability because they tend to wear out sooner than their silver counterparts.  They usually last an average of 5 years or less particularly if used for large cavities. They also cost more than silver fillings.

Whichever type of filling you choose, it’s always best to remember that good dental hygiene is the best way to maintain the health of your teeth.  Brushing at least twice a day, flossing, and regular visits to your dentist always saves you money, pain, and anxiety in the long run.
