Free dental care in Canada?

I'm 18 and I really think I need to see a dentist. My 2 front teeth are slightly loose and there is some decaying on the back. Needless to say I don't want to lose them. Since I do not have the funds nor does my job provide benefits I was wondering if there is anyway to see a dentist for free in Canada(Ontario specifically). Please help.
--------------------
Not free but most Universities that have a school of dentistry have low cost public clinics, where dental students, under the direct supervision of Dentists do work. They are located in major cities, like Toronto, Ottawa, Kingston, London and Windsor. Most local Dentists will arrange a payment plan with you, where you pay by the week, for their fees. Jim B.
