I have what I am sure of is a cavity. What can i do with no dental insurance?

i have a hole in a tooth in the back of my mouth. I am currently a student living in Oregon w/ no health insurance and no source of income. What is the cheapest way I can see a dentist to fix this problem. I love my teeth

well there's nothing you can really do but go to a dentist or look for colleges who offer classes for dentist and see if they offer low pricing for there students to check you and work on you.
