You make great points! It also reminds me, many dental procedures like extractions, crowns and root canals are paid mostly up front, require insurance approval and involve more than one visit or are hours long. I'm also sure insurance requires things to be done in a certain manner/time period. Also, people fear the dentist, it's hard for patients to jump from dentist to dentist and I think insurance companies require the dentist who started the work on a claim to be the one who finishes it unless it's a referral? I'm really not sure, but at any rate, I can see why the people in the office were so concerned. Maybe it points to guilt but maybe not.
