One of the dentists I shadowed was caught using drugs while operating on patients. I wanted to have three types of dental practices on my application to show that I really looked into the different types of dentristy I could go into. The dentist that I shadowed, who lost his license, was a sedation and anesthesia specialists. I have more than enough hours but I really want to include these in my application. Will dental schools view these as valid since he is no longer practicing? I can't even get a hold of the guy to verify my hours.
