If you are over a certain age, you probably remember having a cavity filled with a metal filling – and you may even still have one or two of these in your teeth. Over the years you may have become frustrated at how that ugly metal is interfering with your smile, and you may even wonder if those metal fillings are dangerous. Read on for some information about metal fillings and the benefits that white dental fillings have over them.
Amalgam (metal) fillings are made of different metals mixed together: silver, copper, tin, zinc, and mercury. Mercury is the main concern of most people, as it is known for causing damage to the immune system, kidneys, liver, and the nervous system. You don’t have to worry – any mercury your body absorbs from dental fillings is minimal. When the time comes to have a filling replaced, though, or to get a new filling, white dental fillings are a much better choice. Amalgam fillings typically only last about 15 years, after which they may start to break down. They are especially susceptible to changes in temperature, which means they easily expand and contract, which can weaken the structure of your tooth and even cause it to break. It also means that the hot or cold temperature of your beverage or food can easily be conducted into your tooth and cause pain or discomfort.
Other people are more concerned about the unsightly appearance of metal fillings than they are about mercury. White fillings, which are made out of a resin compound, blend in with the tooth and can even be made to precisely match the color of your teeth. If you are concerned about keeping your smile beautiful, white resin fillings are an obvious choice.
Amalgam fillings are unattractive and can cause problems. White dental fillings are durable, safe, and blend right in so that no one will even realize you have a filling.
