and use of a drug not used in pediactric dentistry or outside of an operating room with a competent anesthesiologist. I'm guessing here, but suspect he didn't want to send me to an oral surgeon and lose the fee, so decided to do it in office himself, without actually knowing the right dose for my size and age.

Sorry 'bout that. I casually mentioned it to my "big sis" a few minutes ago, via messenger, asking if she remembered that incident happening and she cleared that up for me. She was an adult with 4 preteens so was in the loop with the details.
