IMO this is a good litmus test for choosing a dentist.
A dentist with nuanced and honest judgment will identify questionable spots, probe them, ask you about your experience (“does it hurt”), and explain the difference between something to watch and when it is actually problematic.
A lazy dentist trying to make a buck will take a quick look and tell you that you have a bunch of cavities that need to be addressed now.
Just like software engineering, there’s always the guy who will recommend kubernetes for every problem, and then there’s the guy who says “ah yeah, you can just do this with a shell script until you need more”
If you live in the US you can report them to your state’s board of dentistry. Not sure how responsive they are in your particular state but in mine they take that stuff seriously.
