you are 100% right in my view. and i have some opinions about it too. for example some people desire to never feel pain but its necessary. i have read about the people with analgesia some of them lost tongue and damaged cheeks because of bite they had not control over. have you ever bitten your tongue? how fast your Masseter muscle stops that's speed of the pain.but what i hate about pain is i can't tell it to stop i just understand your message :D . for example stop pain i don't care about this teeth i have to remove it anyway or something like it :D
