Dental hygiene and soap

I don't know if you have heard but apparently the state of our mouth says a lot about our health. Oh damn it! I had not been to the dentist in years because of all my travelling. But since we moved to Edmonton we took up going to the dentist again and while I do it with pleasure because I think it's (supposed to be) good my husband dreads it. Also, I had heard before that brushing your teeth AND flossing are more important than the paste on the tooth brush. Reading the Epoch Times today I find that on the health page we are now advised to brush our teeth with  soap. Oh! And don't always believe the dentist!  
I wonder if organic toothpaste comes closer to soap than ordinary toothpaste? Anyway, the advice comes from Dr Gerald F. Judd, emeritus professor of chemistry at Purdue University. I wanted to pass on the reasons why soap is better, not tastier (although honey oatmeal soap might not be bad), than toothpaste.             
Acid destroys enamel and cavities would vanish if one simply rinsed the mouth with water right after eating instead of brushing the teeth. Glycerin which is part of every toothpaste stops our teeth from rebuilding enamel because they are coated in it and and it's hard to wash off due to its stickiness. He also says that bacteria are unable to destroy enamel but soap destroys bacteria and viruses and even removes plaque stuck to enamel. Removing plaque is important to prevent the plaque from spreading onto the gums resulting in poorly anchored teeth. Fluoride, already reason for lots of controversy, makes enamel weak and brittle as well as getting rid of 83 enzymes including the one needed to provide the phosphate for the enamel. (Note: Europe is "fluoride-free" already.) Fluoride reduces indeed tooth decay but several studies have found no evidence that added fluoride (in tap water or toothpaste) is in fact beneficial. 
Got the soap -  I suppose baking soda mixed to a paste with water will do? Got the brush? Go clean! 
And no, organic toothpaste is not much better, it still got glycerin in it.
