This is a great way to stop a toothache dead in its tracks. It works for about 6 to 8 hours, which is enough to let you get some sleep. You simply need to get your hands on an Advil (or other ibuprofen liquid pills).
Make a small hole in the end with a sharp knife or razor blade, just enough so you can insert a toothpick in the end. Stick the toothpick into the pill and get a drop of the liquid onto the toothpick then let it drop onto the tooth that is giving you trouble.
Beware not to let the liquid drop onto your gums or cheeks, as it will burn. It’s a good idea to bite down on some paper towel or cloth for a few mins after applying the liquid to your toothache to stop any runs, then you should be good to go.
