Depending on the toothache and the cause raw garlic may help. I cracked a molar exposing a cavity and some nerve. I had been told to chew on or smash raw garlic and let it sit on the tooth/hole, but didn?t believe it would work. It was still two weeks until my dentist appointment for an extraction. I was trying everything: orajel, even putting oral wax in the hole. The orajel was temporary and the wax only made it worse. I did some research and true enough garlic and onion have been used for 100 yrs. the garlic did help. Here?s the website I used :https://www.angieslist.com/articles/toothache-home-remedies-work.htm
Second, i've had chronic tooth pain since i was a little kid. I'd take several advil if you can, or see a doctor if you think you need something stronger.
