Since fillings are so common, chances are that you’ve had, or will have, a dental filling done at some point. It may feel like once the filling is in place you can simply forget about it, but this isn’t the case. Dental fillings require careful upkeep and will eventually need to be replaced. There are, however, certain measures you can take to keep your fillings healthy and long lasting. Depending on the size of the filling, you may also want to consider getting a crown as a better, long-lasting alternative.
