anesthesia
"I was administered this for removal of my wisdom teeth.  I didn't even realize I had been knocked out because I was looking at my mother one second waiting on them to start the procedure the next second I thought I was still looking at her asking when are they gonna start she said it was over! I felt great I jumped up and hugged my dentist and told him I loved him lol I was so nervous before hand and was so relieved that the procedure was over!"
