“How do you get rid of a tooth abscess without going to the dentist?”

I hate to tell you that you can’t get rid of an abscess without going to the dentist, but you really can’t unless you want to take your own tooth.

Antibiotics would get it under control, but you will need to see a dentist.

To get rid of a tooth abscess the cause of the abscess needs to be eliminated. If it is an infected tooth, I suppose you could removed the infected tooth yourself without going to a dentist but I'm guessing it would be painful and likely to cause other complications. Definitely not advised. A dentist could possibly remove the part of the tooth causing the infection without removing the entire tooth. While taking an antibiotic may eliminate the abscess for a time, unless the cause is eliminated it will return.

You can't. It will not go away unless tooth is treated. Antibiotics will make it feel better for a while but won't cure it.
