Help to get dental work

I have never had dental insurance, and was never taken to the dentist as a minor. I have been suffering from cavities and tooth decay for years. I am currently a full time college student, and while eating last year, I had a tooth break. I didn't have the money to get the tooth extracted at the time. I started looking for part time work, but everyone in my area is only hiring full time, or will not accomidate my school schedule. I have been living with this by eating only on one side of my mouth, and brushing and flossing after each meal, but it is sometimes very painful and bleeds. I have never been a person to ask for help, but any assistance anyone could give would be greatly appriciated! Thanks for reading this!
