I found out as a young girl that I needd several shots to deaden the area b/f the dentist could go to work. The dentist I had then never doubted my word, always made sure I felt no pain. Yrs later I had a dentist who gave me one shot and refused to give me a second. I told him I generally need at least 3-4 shots. He smirked and said, NO, You don't. I said I have always had several shots, 1 doesn't help me. He finally had to give the extra shots, since I had such tremendous pain. He said I was too sensitive. JERK! I never went back to him. The next dentist gave me the extra shots and did the work. No problem!
I have had problems w/ meds, either a reg dose is too much or too little. I had no idea of FMS when I was a child, I was usually very comfortable w/ my teeth being worked on, I never dreaded a dentist visit - till later. The only problem I remember w/ the extra shots was my bottom lip blew up something nasty. I couldn't feel it for hrs, so I kept rubbing it w/ my tongue and upper lip. I had the Angelina Jolie look going for me as a 10 yr old.
I never had an infection when I had a dentist appt.
God bless. Alice.
