I started dental assisting for a Dr. who liked to start with a clean slate, aka no training. The pay was **** at first but I learned so much it was so worth it. I worked part time (20 hours) per week for 1.5 years of college. He also paid for me to get my X-ray license and coronal polishing license. (Easy classes, very simple). Now I work full time for a cosmetic dentist in downtown SF and make bank, so it was totally worth it. I see adds on craigslist about once or twice per week advertising for a dental assistant with no training, keep an eye out for something like that. Best of luck, pm me with any questions.
