Good advice.

Im at a well known megaprofessional dentist,priced "a little above the average" if you want something unusual.

One day, we started to initiate "small project" for some teeth, involving some additonal costs for "beauty-stuff". The accounting appartment(!!!!) of them adviced me to get whatever-XY-insurance before the first step is done to save some costs. On the first day in the morning when step 1 started, I talked to the doc about this advice - she said: "I do not know what they thought but this is a dentist, not an insurance reseller. I do not suggest to do this, you wont need it in your case."

Since then, I never went to another one.
