My dentist was a she and she sure nuff was pure n pretty so I never asked questions because the doctor knows best.
Actually she just performed the services I demanded, never 'sold' me anything.
I was a dental tech in the air force 73-74 so I already know what lurks in the mouths of most and it ain't purdy.
It got all the metal and dead tissue out, still have all my own originals cept one crowned implant, no gum issues, no complaints.
BTW - also had my Amalgams removed same way everybody else does when they get a filling replaced, drill baby drill, no high dollar mercury protection, no side effects like I was forewarned of.
Imagine there are many who just never get it done either because they can't find or can't afford an 'organic' dentist. Which is worse? Just do it!
