I used to get my dental work done at a student clinic, so it was often dental students doing minor procedures supervised by much more experienced faculty. I remember overhearing one explain to a student that different people and mouths have a different standard of what's acceptable. Someone who meticulously brushes and flosses and spends top dollar fixing every problem as soon as it comes up is likely to want a procedure like you described. Someone else who barely has any dental hygiene and a mouth full of fillings and gingivitis would be given all necessary care, but not necessarily given an exhaustive touch-up if the dentist feels they'll just be back for the same thing in a few years and not get any substantive lasting benefit from it. I don't know whether this is a generally-held attitude in the profession.
