I had to make an account to post on here, the tone is wayyyyyy too negative here. Anyone who turns down a dental school spot because of 250k tuition is a financial idiot. Period. I guarantee, if money is your motivation and you are willing to work away from the big cities, 200k first year is not an unrealistic figure. There are many areas in canada where you can make 300k as an associate working 40 hrs/wk, even 400k if you are working in Alberta. That's just as an associate. If you are a practice owner the sky's the limit.
If you decide to work rural for a couple years you can easily pay off that 250k debt in two years. Sure, if you are dead set on living in Vancouver or Toronto then the first couple years you won't make that much, but even a couple hours drive away from major cities you should be able to find jobs where you can make ~150k.
Depends on what country they were trained in. Australia and the US, I would say are equivalent or slightly below NA. I definitely would not hire an international dentist who graduated from India. Just based on what I've heard and from the work of my international classmates in dental school, their standards are definitely not up to par.
