I've had only 2 visits in the past 27 years. I just can't force myself. T-boning a Subaru at 50mph is literally less painful. I'd much rather try my chances at surviving that again, than go to a dentist.
Once I had the "doctor" numb me on the left side, then proceed to pull two teeth on the RIGHT side. I was confused, but I figured "hey, he's the doctor...." I don't remember doing it, but I punched him in the gut hard enough to put him down for a while, and I was only 15. All I remember is the sound of a "crack!" and a mouthful of pain and electricity and copper taste, and then him moaning on the floor. Having teeth pulled w/o anesthesia is really painful.
I've told just about every single moron-with-a-drill that I'm resistant to procaine derivatives, and I've had 85% proceed to tell me that I'm numb and I'm "imagining it" and try to do whatever. Once I screamed so bad, that my friend told me three people left the waiting room because of it. I've *never* had anyone offer to knock me out. I've asked and been told "that's not necessary"
I had one dentist that could actually give injections without pain, and actually changed anesthetic when I didn't go numb, to something that actually did the job. The ******* then proceeded to retire 3 months later.
I had one guy about 2 years ago do a terrific job of putting in a crown to replace a rear molar that had shattered 22 years ago, but I have such a fear that I can't get up the courage to go back. I really need to, because I have one tooth that's rotated sideways, and one tooth that's missing about 2/3rds of itself. I just can't.
You definitely have my sympathy!
