Excellent post and results! Everyone should know this - dentists just reflexively tell you you need a root canal if there's any sign of tooth infection. I even spoke with a dental student that said she was taught that no tooth infection can be healed - it will just appear later (kind of like being in remission).
Ridiculous! Pack some Bentonite clay between the cheek and gum where the abscess is, and it will be history in 24 hours. Works the same way for drawing out tooth infections. But dentists will never be able to make money with it so you'll never hear about it from them.
