Dr. Jen's Fluoride-Free 10% Premium Nano-Hydroxyapatite Toothpaste is a fluoride-free toothpaste made in an FDA-registered facility in the USA, formulated at 10% nano-hydroxyapatite (nHAp) — the same mineral that makes up tooth enamel — and described by the manufacturer as the first and only fluoride-free nano-hydroxyapatite toothpaste with a naturally derived formula at this concentration. The nano-hydroxyapatite used is EU-certified, rod-shaped crystal nHAp at premium grade. The formula also incorporates xylitol and a proprietary essential oil complex. The Cool Mint variant contains peppermint oil (Mentha arvensis) and spearmint oil (Mentha spicata) as natural flavoring and freshness agents, along with botanical extracts including anise extract (Illicium verum), papaya extract, and black cherry extract. The Strawberry variant features natural strawberry flavor, citric acid, and calendula extract. The Watermelon variant features natural watermelon flavor. Base ingredients across variants include glycerin, water, hydrated silica, xanthan gum, and potassium sorbate. The low-abrasion hydrated silica supports everyday polishing, and the formula contains no SLS, no titanium dioxide, no artificial color, no propylene glycol, no artificial flavors, no pain blockers, and no fillers. Xylitol is included to support oral microbiome balance. Dr. Jen's is developed and owned by a dentist and is recommended and used by dentists. It is designed for anyone who chooses fluoride-free oral care, whether for cleaner ingredients, specific wellness approaches, or advanced fluoride-free performance. The toothpaste is formulated for twice-daily use as part of a consistent brushing routine.
