Mouthology

Mouthology 10% Nano Hydroxyapatite Toothpaste Fluoride Free, Whitening*, Rod Shaped nHa, Xylitol Toothpaste for Adults, Enamel Care*, Sensitive Teeth*, SLS Free, Mint 4oz (USA Made) Package May Vary

Why we love it
  • NASA-inspired enamel repair technology.
  • Clinically proven 10% effectiveness.
  • Fluoride-free and safe for everyone.
Main Highlights
  • 10% NANO-HYDROXYAPATITE: Our toothpaste features 10% nano-hydroxyapatite (n-HA), a calcium-based compound used in Japan for decades in oral care. Known for its smooth feel and gentle cleaning, n-HA is an alternative to fluoride for those who prefer fluoride-free options. n-HA is a remarkable biomaterial that comprises 60-70% of bone mass and an astounding 96% of tooth enamel, making it the hardest substance in the human body.
  • WHY 10% SPECIFICALLY?: Unlike other brands that hide their Nano-Hydroxyapatite percentages, our toothpaste contains the full 10% Nano Hydroxyapatite—the optimal amount concluded my most scientific studies. Too little is ineffective, and too much nHA starts to aggregate (or "clump" together) also reducing efficacy.
  • THAT CLEAN DENTIST FEELING: Say goodbye to harsh bleaching agents. Our nano hydroxyapatite toothpaste gently polishes, leaving you with a glossier, smoother "tooth feel" without causing sensitivity.
  • FLUORIDE FREE & SAFE FOR ALL AGES: Our nano hydroxyapatite toothpaste is completely fluoride-free, offering a safe alternative for those looking to avoid the negative health concerns of fluoride. Our nHa toothpaste is made with biocompatible ingredients, safe if swallowed and recommended by dentists nation-wide.
  • MADE IN USA WITH CLEAN INGREDIENTS: Made in the USA with premium, globally sourced ingredients. Our toothpaste is fluoride-free, SLS-free, with birch xylitol to promote oral health. No artificial colors or flavors. No Triclosan. No Titanium Dioxide. Just clean, gentle care for your mouth.
