Few people realize that a filling does nothing to prevent another cavity. Cavities are caused by bacteria (germs) that live in our mouth. These bacteria infect our mouths as soon as we have teeth. The disease they cause is called caries. The acids and metabolic by products of these bacteria attack the teeth and gums. For the teeth the end product of the disease is a hole in the tooth; a cavity.
When you think about it, cleaning out that hole and patching it with a filling does absolutely nothing to stop the bacterial disease that is active in your entire mouth. As a matter of fact, the edge of the filling, no matter how good the filling, is a perfect niche for the bacteria to gather and begin eroding the tooth down the side of the filling. The result is a new cavity under the filling! Very discouraging.
The answer we all want is how to control the disease. If you are willing to dedicate 2 minutes of your day to the job you can control the disease. Controlling the disease means no more cavities. Even for people at high risk for cavities the disease can be controlled and cavities prevented.
Most people brush their teeth but do not get their teeth adequately clean because they have never known how to measure how well they are doing. When you establish a relationship with a dentist the very first task should be to learn from the dentist, hygienist and staff how to control caries (the disease) in your mouth. Any fillings done before the disease is controlled are at high risk of failing because new decay will invade the edges of the filling.
People who control the disease can get their fillings with confidence they will last for a very very long time.
If you have not learned from your dentist how to control caries in your mouth and how to measure at home how effective you are, then that is the first thing you should do, before more cavities are filled.
