Please tell me, are there any online dental assisting programs?

Internet Search: Use your favorite search engine to inquire. Truthfully, you would need experience learning in an actual dental setting. The tasks you would need to learn require that you actually practice them, not just read how to do it on a computer screen. All the best...

Not accredited: Dental assisting is literally a hands-on discipline. You can't just read on a computer screen about doing a procedure, you actually have to do it to learn how. Check with your local community colleges or call your local dental society to ask about training programs in your area.
