How long do dental fillings last?

The length of time that your dental filling will last will vary depending upon the size of the filling and the material used. If you use a filling material that is designed to be a small filling and you use it as a large filling, it's not going to last as long. The average length of time in the state of California and that's all I'm familiar with, for a filling is three to five years. Not a very long time, although many fillings last twenty years and longer.
