Well best of luck there mate, I wanted to point out that I have just graduated from dental school, but the last two years I studied I did get into clinic training, I extracted, did cavity preps, made prosthetic dentures ...etc all of course with the help of actual dentists, however I still had to convince people to train on, I didn't always face a problem explaining what their teeth needed but the pressure got into me when I was for example under the microscope of an a**hole dentist, and we have alot of them at my college, it made it 10 times worse for me, not only I had to communicate loud and clear but I also had to report back to my dentist superior in detail of what I'm doing and he/she had to come and see the patient in every step I'm doing, it was a terrible experience for me, i was already anxious enough as a student and as a stutterer, I'd choke on some words, including my name. We had this system where when we finish our work, we hand the instruments back to the (let's call it the autoclave center, that was ran by assistants) and I had to tell them my name, I choked probably more than a dozen time, especially when I was nervous. It was no pleasant experience for me, even when I achieved aomething, it didn't help much with anxiety, I always wanted to change that, I failed big time. How am I gonna be a doctor you ask? I have no idea, and I'm terrified.
