Davids Hydroxi™ Sensitive+Whitening Toothpaste brings cutting-edge enamel care to your daily oral hygiene routine. Formulated with nano-hydroxyapatite (nHa) — a naturally occurring mineral that makes up 97% of tooth enamel — this premium toothpaste is designed to support stronger, smoother, whiter teeth.
Originally developed by NASA to help astronauts maintain healthy teeth and bones in zero-gravity environments, nano-hydroxyapatite is now recognised as a breakthrough ingredient in modern oral care. Its microscopic rod-shaped particles work by bonding to the tooth surface, helping to fill micro-imperfections and smooth the enamel for a naturally brighter, healthier-looking smile.
Supports Enamel Health: Nano-hydroxyapatite helps replenish and strengthen the tooth surface by depositing the same mineral your enamel is made of, supporting long-term oral wellness.
Natural Whitening: Ultra-fine natural abrasives from calcium carbonate and hydrated silica, combined with coconut oil, gently lift surface stains to reveal a brighter smile — no harsh bleaching agents needed.
Gentle Formula for Everyday Use: Free from fluoride, SLS, sulfates, artificial flavours and preservatives. Formulated with naturally sourced ingredients including birch-derived xylitol, which helps maintain a healthy oral environment by supporting plaque control.
Fresh, Clean Taste: A premium blend of natural peppermint, spearmint, wintergreen and anise oils delivers a refreshing, cool finish without any artificial aftertaste.
Sustainable and Ethical: Vegan, cruelty-free and Leaping Bunny certified. Packaged in a recyclable metal tube to reduce plastic waste. EWG VERIFIED™ and USDA certified biobased.
