Thanks for bringing this up. For as long as I've been soaping, I've heard about tooth soap (only in the context of having skimmed over the title of several threads, but without ever having been interested enough to open them and read through any of them, lol), but following a crazy hunch yesterday I opened up your thread, and I confess that I found myself intrigued enough last night to read through almost all the threads about it here on the forum, and also on another soaping forum.
My hunch revolves around what my dental hygienist told me a few weeks ago during my regular 6-month dental cleaning/checkup (no cavities, btw- yay!)........
She told me that when it comes to cleaning my teeth, she always seems to spend most of her time time scraping off hardened build-up caused by acids in my mouth.......
Even though I practice very good dental hygiene by brushing with my Sonicare and a 'good' toothpaste and flossing & rinsing at least twice a day (which is great at cutting down on bacteria and keeping my mouth clean), she told me to really focus my attention during those in-between brushing times on reducing the amount of time acids sit around in my mouth.
She told me that bacteria and acids are two different things that need different approaches. The approach she recommended for me to help reduce acids during those in-between times throughout the day is to use products with xylitol in them (they make all kinds of things with xylitol nowadays- gum, mints, toothpaste, mouthwash, etc..). She told me she's found it to really help at keeping those acids from taking hold and causing chaos.
Anyway, I could be wrong, but I'm thinking that the alkaline pH of 'tooth soap' might be playing a part in acid reduction.
For what it's worth, I've decided that I'm going to HP a sample batch of judymoody's posted recipe for her tooth soap, and include it as part of my regular/normal regimen for a while- i.e., not 'instead of', but just a 'part of'.....at least for now anyway- we'll see how my next appt. goes in January.
