Get a second opinion. When we moved to our town 20 years ago, we tried a new young dentist with an office in an expensive medical building. He said I'd need most of my old fillings replaced.

I hadn't been ignoring my teeth and in fact had had regular dental visits before moving there.

We decided to try another dentist, one who attends our church and has a small and modest office. He said my fillings were fine and all I needed was a cleaning and checkup.

There's no way I'd believe that dentist under the circumstances, it sounds fishy to me.
