Anyone know how to get Dental help in Boise, Idaho with no Insurance?

Im 29 years old. I have not been to the dentist since the early 90's when I had my braces taken off. I recently went to a Local Dental office because of a coupon I received in the mail... To my surprise I have only 4 cavities...not bad. But I guess I have periodontal issues and a severe case of Gum Disease. They are recommending that I have ALL of my teeth pulled and that I either get Dentures or Implants. I don't have insurance, not even medical. I am Diabetic, and have a hereditary health issues that also coincide with that. ANyone know how does a person get good...if ANY dental help in this day and age? I Also don't have a lot of money...and that Dental Care credit thing is out.
