The OP's post said: "I don't doubt that loans will be available, but for any current BU students or any BU alumni- are you having a hard time paying them back?"
He knows he can get loans, he is worried about paying them back.
OP, you should have no problem paying them back, just don't take more loans out than you need. You can consolidate your loans after graduating.
I was working numbers out myself and I would have repayments of about $1900 a month (total of about $260,000 in debt)
So: from the ADA 2008 Survey of New Dentists, which is available from the ADA:
(I am pretty sure you need to be a member of the ADA to pull these off the website)
The average hourly rate for associate GP's is $68 an hour, which is about $130,000 a year.
Assuming you made just under that, $120,000 a year, thats about $7,724 a month after taxes.
You should be able to pay out $1,900 a month and still have $5,800 to live off of and save up for purchasing your own practice eventually.
Now this depends on how much you end up making, the kind of lifestyle you like to live, and how much you take out for school.
But if new dentists weren't able to pay off their loans, they would not be going into dental school to begin with.
