Hi,
I recently had the same problem. I chewed on echinacea root for a week every day & was able to clear up the absess & had the tooth filled instead of a root canal. It helps with the pain too. Also, I drank alfalfa tea which is good for the teeth. I would also like to add that I do "green" drinks almost every day lately which I'm sure helped! I make them with kale, apple & lemon juice. Hope this helps! Sandy :)
