Hi everyone. Dr Steel23 here.
I just found this thread and would like to comment. As in all medical fields, there is often a large discrepancy between the "holistic approaches" and true evidence-based clinical practice.
The information you have been reading is, unfortunately, anecdotal at best and drivel at worst. The man with the PhD who preaches it is a joke who I'd guess holds stock in the soap that he wants you to brush with.
Glycerin in toothpaste does NOT recede your gumline or ruin your teeth. Nor does it leach fillings or loosen teeth. Glycerin in oral products is used mainly for its lubricating properties with no ill effect. As one small example, my oral surgeon colleague and I often treat radiation patients suffering extreme dry mouth due to a complete loss of their salivary gland function. We supplement their treatment with a water/glycerine mixture and combined with proper hygiene, their oral improvement is rapid.
But glycerin is not the demon you believe it to be. Your loosening tooth and receding gum line are from other problems. See your dentist.
On the suggest of
vaping, I can’t give you long-term data because there is none. I am also unaware that vaping would dehydrate you. But if you insist on vaping and find that it dries your mouth severely, ask your dentist for a bottle of Biotene (which coincidentally, also has PG in it) and rinse with it periodically. It won't hurt you.
Hope this helps.
