H.D.
I am a dental hygienist and would be willing to answer any question you or him might have. As far as I know, Collin County and TCC have 2 yr programs and TWU and Baylor have Bachelor programs. There is training involved you just can't take a test. Dental assistant school would be of some help learning to take xrays but is useless other than that. They teach you to take xrays in hygiene school so you should just go to hygiene school. They are very selective on who they let in. You must have a very high GPA and most want all your basics taken before you apply.
