Are your fillings metal or do they match the color of your teeth? People often ask me about the difference between metal and tooth-colored fillings. It’s a good question.
When dentists fill a cavity, they first remove the decay, thoroughly clean the area, and fill the cavity with a filling material. A good filling will last anywhere from 5 to 50 years. If you’re going to have a filling in your mouth for that long, it’s fair enough to want to know what it’s made of and how it compares to other types of fillings.
The two most common filling materials dentists use are silver amalgam fillings and tooth-colored composite fillings. Let’s look at the pros and cons of each filling type and why dentists sometimes choose one over the other.
Silver Amalgam Fillings

Your dentist has to remove more tooth structure ensure a long-lasting filling dental supplies. Most dentists will tell you that removing less natural tooth structure is generally better when possible.
Amalgam fillings aren’t like your natural teeth.
Amalgam fillings expand and contract differently than the tooth itself, so we sometimes see cracks in the natural tooth around a silver filling as a result of this difference in expansion and contraction. This can eventually lead to decay forming in the cracks, tooth sensitivity, or tooth breakage.
That’s just one reason why it’s important to see your dentist regularly so he or she can check out your fillings.
