When I was a kid our dentist charged $7 ($8 if you needed a filling - done right then). He NEVER used pain killer. I recall one front tooth he drilled just above the gum line when I was a teenager and I pulled the cushion arm right off the bracket on the chair. God, that was torture.
Matter of fact, I still have that and other fillings he put in. Those used a mercury/silver amalgam that a little machine would heat and shake up before he packed it into the cavity. I'll give him that - his work lasted.
I never had Novocaine until after I was married and had my wisdom teeth pulled. And I had a LOT of cavities as a kid. That which does not kill you makes you stronger.
Pain makes man think
Thought makes man wise
Wisdom makes life endurable
