I learned that dentists make their money by doing procedures that have little overhead and high returns. I read about patients who would go one dentist that said they found X cavities and then go to another dentist that would say 'zero' were found. I tested it myself when I was told I required extensive cleaning beneath the gums and the next dentist, who has a 3 month waiting list, said it was not required and my teeth were fine. I no longer believe any dentist and considering most are now private equity operated it makes sense.
