My mother is in serious need of Dental care. I am curious to know if there are any pro bono dentists in Canada?

If anyone could point me in the right direction as to where to investigate either dentists, colleges, or community heath care services that offer pro bono work, or something of a lower cost in Canada, that would be of so much help! Thank you.

try dental schools thats your best shot. they will give you a better deal then the dentist office. Try U of T if you're in Toronto area or Western if you're in the London area.
