I don't know how much is bad for the teeth.
It's added glycerin that is the problem not what is already in the soap.
Everyone I've given or sold the soap to has said that their teeth have never felt so clean.
You can actually feel that your teeth aren't been coated with glycerine unlike with toothpaste.
Like I said before, I'll never use toothpaste again.
20g lasts me and my boyfriend months - way cheaper than buying tooth poison, er, paste from the supermarket.
Interestingly my soap maker in the US had never tried it before making it for me but now she's hooked and the the lady who used to make it for me here couldn't bear the thought of putting it in her mouth.

Well, I'm going to dig into my box of old soap. They were all EO soaps, although not peppermint. I'll give it a try and report back tommorrow.
Peaches, did the soap have salt in it? I doubt it will be hard to get someone to make it here. Its a simple recipe 

no it didn't have salt in it, just the ingredients in my previous post.
Try brushing a couple of times before deciding whether you dislike it or not.
A word of warning - don't use too much - it's a bit unpleasant if you do!

if 20g lasts you months, can you not just keep buying from the US??
I doubt whether it would attract import duties & would be cheap to send over. The £ is so strong against the $ too.

Good point K.  What sort of quantities are you looking for peaches?

Think she bought a kilo!
Thats a lot just for teeth 

Not if it's for selling on though.

Or is that just for the other stuff Peaches?

Just picked up on this thread and am not sure if I like the idea of cleaning my teeth with soap. But must admit I have been concerned with what is in toothpaste recently.
My dentist gave my grand daughter fluoride tablets and said all children should have extra fluoride but I do remember a case many years ago of a teenage girl with bone problems which it was reported was caused by fluoride tablets, so I did not give them to my grand daughter (fluoride occurs naturally in food.)
Will give it a go. Can't knock till you tried it.

I don't get why cleaning your teeth with soap is such a horrible thought - it foams -  just like toothpaste but you wouldn't want to swallow any - just like toothpaste.
It's natural - unlike toothpaste.
I need a kilo at a time because I sell it on - so there is a market for it!

Please take a look at www.fluoridealert.org
Fluoride is a by product of the aluminium industry - a poison - and it's in your toothpaste!

Neither fluoride nor silica are in the toothpaste currently in our bathroom, there is glycerine.

Are there any brands of regular toothpaste that don't have all the bad stuff or less of it?
Haven't yet dug out my old soap to clean teeth with, but I will give it a go.

Have dug out some old peppermint soap....still think this is a wierd idea 
(but will give it a go).

Can I just ask, is there any consequences to using such an alkaline product on your teeth and gums?  I wonder what the pH is of regular toothpaste compared with this is.  I'll go check mine.....

Ok, this has surprised me.  I had visions of regular TP being slightly alkaline but actually, mine is acid (pH5.5).  I am genuinely surprised by this.

Elaine it doesn't have to be listed if it's less than 1%.
I've researched this and the only toothpaste that fits the bill is this one:-

It doesn't foam and it's a bit salty for me (due to the sodium bicarbonate) so I prefer the soap.
