How can you kill the nerves in a broken tooth at home?

Ok before I start I want to make it clear that I know I should go to a dentist instead of doing this on my own, so please dont tell me that. Reasons I wont go are: 1. I’m deathly scared of them due to an experience with a quack dentist that left my jaw messed up. And 2. I don’t have the money for one.

That being said I have a broken molar that half the tooth is gone now and has been broken for a while, the root is exposed and just now starting to REALLY hurt on a daily basis. I have one other tooth that the same thing happened and I didn’t go to the dentist for. Eventually the whole tooth broke off and nerves died so there is no pain or any issues with that one. Which I expect will eventually happen with this one.But my pain tolerance isn’t the same anymore and I cant deal with the pain on a regular basis. I’ve read a lot of home remedies online and they all say things like clove oil, vanilla extract, tea bags, etc. But those only stop the pain. My friend said holding a shot of tequila or whiskey on the tooth will kill the roots/nerves.

Has anyone on here killed their tooth’s roots/nerves at home? If so how did you do it? I don’t care how painful it was.
