I’ve had several, due to childhood trauma making me not take care of my teeth.
It’s a lot better these days. They numb, and if I say it still hurts, they get more novacaine into the tooth. They also listen when I say I need more than typical because of genetics.
Also my primary doctor gives me xanax. It helps.
For me it’s three visits for each root canal. First is the drilling, second is the temp plastic cap, third is the permanent cap. Third is very quick cause is just putting it in basically.
I only know of this book because it was included in a Showcase Showdown style…thing I saw once, where everything in the showcase was…well, if not bad, highly impractical.
Mostly bad.
