I went to dental assisting school and got my radiology safety certificate. I agree that it's not worth it if it's a financial burden for you. What you learn in dental assisting is only the basics which you can study on your own and your classmates will catch up quickly. I worked as an assistant for a great mentor for somewhat less than a year and learned about healthcare professionalism, teamwork, leadership, business management, patient communication, and other aspects that may help you to form your own practice style once you graduate. You may have some difficulty in finding a dentist willing to train on the job; you will learn more quickly than someone with a career goal of being an assistant, but you will be leaving for dental school and your doctor will lose his/her investment in you.
Does anyone have any good experience as a lab technician? Without training, wouldn't you only get to pour plaster, mount casts, and manage cases? Anyone learn to stack porcelain, fabricate frameworks, or dentures?
