After having a very difficult extraction of two wisdom teeth growing sideways, my dental surgeon told me to take pain killers before the freezing came out. Since I don't take pain killers, I sliced a thin piece of garlic and placed on both extraction stitched wounds as the pain became unbearable. First it burned slightly, then the pain lessened so I did not need to take pain killers. I continued to replace with fresh garlic slices for a couple of days. The healing process was also unbelievably fast. The dental surgeon couldn't believe the results.
