I did 20 hrs of shadowing about 2 yrs ago. I was just standing next the dentist and was watching what he did. I was not able to help him doing surgery, cleaning, x-ray...nothing. I happened to have another shadowing chance coming next week and I want to get prepared this time because this dentist will be the one who will write me a letter of recommendation in 2 months from now. Letter of recommendation is due on May1st meaning he has to send it early april and then he should start writing it around march...so I can only let him know about me for about 2 months and I wanna give him a good impression. what are the suggestions? At first, I wanted to ask him many questions but he said he will be too busy next monday but if I want to come in and observe him he said I can. That's why I am going but I know that he will be too busy to answer my questions.
