Several months ago I ran across a post on the blog Goofy Momma. Allison shared information about glycerin in toothpaste and how glycerin coats the teeth and keeps them from remineralizing. I had never heard of any negatives for glycerin and actually hadn't realized that it's in nearly every toothpaste, natural or not. I always overlooked it when reading toothpaste labels and yes I ALWAYS read toothpaste labels. I will not buy a toothpaste that has fluoride or if at all possible sodium laurel sulfate in it. I'll share why in another post on another day.
When it comes to our health, there is a whole lot of contradictory information. For every "fact" that exist you can almost always find information that contradicts it. Taking a closer look at glycerin and it's affect on teeth, this is defiantly one of those topics that includes a lot of contradictory information. In the end you will have to use your own judgement and research to decide what is best for your family and you. When searching how glycerin affects the teeth, there are plenty of sites which include information on how glycerin can block the teeth's ability to remineralize. The belief is glycerin leaves a thin coat on the teeth, keeping the teeth from having the natural ability to remineralize, which happens from the saliva in the mouth. I have read in numerous places that it can take anywhere from 20 - 30 times of brushing without glycerin to remove it from the teeth. It seems that the bases for this information comes from the research of Dr. Gerald Judd.
