Bests & Worsts Reviews from Amazon

Putting aside the taste and consistency, the combination of ingredients makes no sense. I reached out to the company over a week ago, asking for an explanation before writing this and got no real response, only a let me ask the product development team and get back to you. Diatomaceous earth (DE) fossilized remains of diatoms. The hardness scale rating of DE is unclear, ranging from 1.5 to 7 depending on where you look and who you trust. Dental enamel is somewhere between 3-4. My dentist said I could use it to polish my teeth occasionally, but not daily. That when I use DE on my teeth leaves them feeling smooth and shiny leaves me to believe DE is harder than dental enamel. Translation: I think my dentist is correct in so far as DE used regularly will damage your enamel. What I take most issue with is the probiotics, coupled with Tea Tree Oil, and possibly the activated carbon. Tea Tree oil is such a strong antiseptic that the NIH has declared it effective against MRSA. It kills lactobacillus at concentrations of 1-2%. Trace amounts regularly have demonstrated negative estrogenic effects on hormones to boot. Translation: Tea Tree oil could be giving me low T. At levels of 1-2%, it would kill off the probiotics I'm pay for in this toothpaste, but in the manufacturers defense it might keep the toothpaste from carrying other dangerous pathogens. The manufacturer claims the probiotics in the product are deactivated. Then what's the point? And activated carbon potentially could absorb the tea tree oil, rendering it harmless, but then what's the point? Bottom Line: This product may appear to work well as a polish, but it may harm enamel, the probiotics you are paying for are deactivated (dead?), It's not cheap, and the tea tree oil very well could impact hormone levels.
