Full disclosure: The reason I was at the dentist in the first place was because my last wisdom tooth had split in half, and needed to be removed. The other three had been removed a few years earlier, but at the time, this one was impacted.

I don't know if that one had cavities or what, but it is true that the dentist said this about my OTHER teeth--it actually worked against me, as it made that broken tooth a lot harder to drill out!

I've had no trouble with my teeth since.
