What is the Lifespan of Most Composite Fillings?If you have ever had a cavity, you know that the best way to restore your tooth is to get a filling. Did you know that there are a couple of different kinds of fillings that you can choose from?

Today we will talk about the advantages and disadvantages of amalgam fillings and resin composite fillings and how long they last.

Get Filled In
Amalgam fillings are what people commonly call silver fillings. While they are not actually made from silver, they are grey in color and can easily be seen. This is one of the disadvantages of amalgam fillings. They are made of a mixture of mercury, silver, tin and copper, which all bond together to make a strong long lasting filling.

Amalgam fillings should last on average 10 to 15 years before needing to be replaced and they are less expensive than composite fillings. Since amalgam fillings have been used for over 100 years, they have become a tried and true staple in our office. But what if you do not want a silver filling, is there another option? The answer is yes.

We also do many resin composite fillings in our office, which many people prefer. They are tooth colored fillings made out of resin that can blend seamlessly with your natural tooth. One of the drawbacks of resin composite fillings is that they only last 5 to 7 years, which means they need to be replaced more frequently. Since the resin material is flexible, it also means that there is less drilling on your tooth, which preserves more of your natural tooth.

In our office, we are happy to meet your needs by providing both types of fillings. If you are in need of a filling, give us a call and schedule a checkup, we can discuss which options are best for you.
