This. And ibprofun or even if you can get to doctors the stronger anti inflammatory, like naproxen, does wonders, in about a day it goes down. But you still have to deal with the pain, so the above is better for you than tylenol 3's by a long shot.

Also, oil of oregano, drops. 3 or 4 drops put into the toothpaste, and a few drops onto the tooth. Once or twice a day.

And seriously. Encourage him to pray and offer all his affirmations or visualizations to the Will of God/Goodness, I affirm, and it works very much, alot of the time, however, I don't like "magic". I place all my thoughts, affirmations, words, visions, prayers, and meditations as prayers in the hands of God/Goodness, under the Will of my spiritual Father, and Yeshua.

Then say, I am experiencing no pain. I have no pain. I am not experiencing pain. My teeth and mouth are healed and healhty. I have no pain. And one can also lay on hands and pray in the name of Yeshua, that it go away. But the affirmations help.

This actually works much of the time. But I still needed teh naproxen on one occasion.
