Yes, it is cheap as chips. I've had some negative responses to my posting from those who think I'm promoting some sort of scam and/or money making exercise. This is not the case, merely want to share my experiences with as many people as possible. Any sort of dentist work costs an arm and a leg in Australia - cleaning is circa AUD200.00 alone and this appears to prevent all sorts of problems and is controlling my continual tooth/gum infections that could only be cured with antibiotics. Antibiotics cost about the same as MMS and you have 2 years supply probably more, for that purpose. If someone somewhere is making money out of this I don't care - the cost to me is buttons! Still getting great results with my teeth.
