bad day

Today I got to watch my patient get a tooth extracted in my chair. It was so infected that I gave him three injections and Dr. Hopkins tried to give him some but he still wasn't too numb. The patient was however very dramatic. He would not let me get him numb but flinched with every tooth I scaled. I have never felt so worthless with my skills as a DH as I did today. I missed stuff on every tooth and it was just terrible I came away feeling that I have failed even though technically since we had to get his tooth extracted, I didn't even finish a quad. I guess I just will definately need instructor assistance when this patient returns since I can't do it myself.
