I just wanted to share my experience with toothaches.
In the past I got the worst toothache in my life. I couldn't even touch my tooth, it was so sensible. The pain was terrible and no pain medications were working.
I rubbed my gum around the aching tooth with a cut garlic (I hit delicately the piece of garlic with meat tenderizer to let juice go. I did it several times and the pain was gone.
On the other occasion I rinsed my mouth with salt diluted in water (I used Real Salt). The pain was gone immediately (but my tooth was aching a lot less this time).
