Mix equal parts of table salt and baking soda, mix dry ingredients together. Dab a cotton ball in water to moisten, dip it into the powder, place between teeth and cheek, DO NOT PLACE INSIDE OF THE TOOTH.
Leave in the mouth over night or for a few hours during the day. This poultice
will draw the abscess out of the gum and will form a pimple on the gum which can be broken by pushing on it. This will relieve the pain and pressure.
When the abscess breaks spit out the poison, it will be bitter, so you will know it is the poison, do not ingest the poison. The cotton ball can be removed. If the tooth does not quit aching, this process can be repeated until you can get to a dentist to get the tooth taken care of.
