Does it come a point when it just doesn't make sense ? I'm 40 now - have been a software engineer for the last 15 years. I would LOVE to go to Dental School! Starting as a NEW dentist at 45/46 should certainly yeild 20 (maybe more) years of practice but shouldn't a new dentist need to bank some experience before opening a practice? When can a new Dent start making a decent buck? Not that I'm thinking of this for the $ (can make more doing what I am currenly doing) but , everyone has bills and newly found student load debt! So, open a practice at 50 - spend 15 years doing it. It's almost like retiring into Dentistry.....
