After you brush your teeth, rinse with warm water. Sip a small amount of peroxide, and let it set on your tongue until it starts to fizz. Slowly rinse one side, and then rinse the other side. It hurts a little at first, but the pain eased off. Keep repeating this until the pain is gone. Believe it or not, it worked for my toothache.

I have to wait 6 days till my appointment at a dentist, and the pain is unbearable, so far I've tried Paracetamol, helps, but briefly. Also, Morphine to various degrees does help a lot, small doses of Morphine sulfate every 4 hours will allow at least 15 minutes to1 hour of numbness, yet the effects of this drug wear off quite fast (this is helpful when trying to sleep, although morphine has some dopey side effects). Alcohol helped, although that I won't recommend. Exposing the tooth to warm and cold water provided very brief pain relief, although even more pain afterwards, especially after warmed salt water.

For toothaches, I find it effective to use onion or garlic and put some salt on it and put it all on the affected tooth, or you can chew it with the infected tooth. Onion and garlic work miracles for toothaches and gum pains.

Extra Strength Excedrin works miracles for a toothache - until you can get to a dentist to get it fixed. I did this for a couple weeks, but once it's deep into the nerve as in my case I needed a root canal - nothing will help, and the pain is unbearable. I'm on another antibiotic and am hoping for some relief till they can get me in for the root canal.

I have many times experienced terrible tooth aches. I would suggest strongly not to rely on home remedies like clove, garlic, cardamom, salt water rinse etc., and seek the professional help of a dentist immediately instead of facing recurrent attacks unnecessarily.
