History of 
Nanohydroxyapatite (nHAp)

In the late 1970s, NASA scientists searched for a cure for Astronauts returning from zero gravity environments that were experiencing bone and tooth enamel loss.

Their treatment included introducing Nanohydroxyapatite (a naturally occurring mineral that makes up 97% of tooth enamel) into toothpaste to help restore and remineralize tooth enamel.

The mineral was so effective that a Japanese toothpaste company, Sangi, purchased the patent from NASA in 1980 to use in toothpaste. The rest is history.

For over 40 years, nHAp in toothpaste has proven to be the most effective solution for helping to stop tooth decay all over the world.

Your oral health is the gateway to your overall health.

Here's something most brands won't tell you: fluoride-free toothpastes are not regulated by the FDA. That means any brand can make bold claims about their ingredients with zero requirement to prove them. In an unregulated market, transparency isn't the norm. It's rare. Dr. Jen's holds itself to a higher standard, backing every formula with third-party research and ingredients you can actually trust.

With many of my patients seeking oral care products free from propylene glycol, sodium lauryl sulfate, and artificial flavoring, I did an extension search on natural toothpaste. Dr. Jen’s was the only brand I discovered using safe and science-backed ingredients. I have seen less plaque build-up and stronger enamel with my patients using Dr. Jen’s. This is the only toothpaste I recommend for my patients.

I found Dr. Jen’s toothpaste was the only brand using proper levels of Nano-Hydroxyapatite to be effective with remineralizing enamel..

I loved the CE. I’ve been in dentistry for 17 years and never knew that my prescription-strength fluoride alone can’t do the job in a dry mouth! We’ve been recommending Dr. Jen SuperPaste for our patients, and they love that they can get it from us or online.

The Dr. Jen Story

When Dr. Jen discovered toxic ingredients in traditional toothpastes after her daughter’s health scare, she created a safer alternative. Partnering with top chemists, 


Dr. Jen’s delivers 10% Nanohydroxyapatite, the gold standard for enamel protection, because every smile deserves the best.



I scoured the internet and health food stores, searching for a toothpaste with proven ingredients. To my frustration, I came up empty-handed. The few brands that did use nano-hydroxyapatite often fell short, using either diluted concentrations or incorrect "micro" crystals that could not match fluoride's enamel-remineralizing capabilities.
