I know that the average dentist works about 4-5 days a week averaging 36-40 hours a week. My question is that does this include administrative duties? Also a lot of salary surveys state that general dentists make about 170K but isn't that for dentist who own their own practice? How hard is it to start your own practice (assuming ma or pa isn't a dentist)? I use to work for a dentist and he told me that it costs about 100K a chair to open a practice and that he didn't see profit until he was in his mid 30s. He's now established and makes bank but he told me it took A LOT of hardship to get there.
