I got in to see the dentist to have some cavity work done. The tooth in question had a rather large hole that was hurting me off and on with increasing frequency, and had recently been impairing my ability to eat or drink.

They numb me up, get started...and pretty much immediately I notice I can still feel something. They numb me up more. They get a bit deeper before I feel something again.

Rinse and repeat several times. My cheek and gum are basically dead to the world, and yet the pain happens whenever they go deeper into the tooth. Each time they can get a little further, but I'm sweating and shaking after a half dozen zings. I swear they pumped a gallon of the stuff into my tooth.

Turns out it's so bad I had to lose the tooth.

While anesthesia wasn't fully numbing it.

And the roots were being stubborn.

Dentist kept apologizing, and there wasn't much to be done as it had to come out.

Haven't been in that much pain in ages. Never want to be again.
