I am a college student (but my parents don't have insurane either so I'm not covered under theirs) and don't have tons of money for the dentist. One of my molars has a little hole in it though so I know I need to go to the dentist. What is the most affordable way for me to have this taken care of? Thank you.

Try going to a dental school.
I feel your pain.
I don't have insurance either;-(
Good luck
