10% Nano Hydroxyapatite Whitening Toothpaste, 3.75 oz, 2 Pack | Fluoride free gentle formula, clinically supported NASA-developed nHA that remineralizes for strong enamel & bright teeth

Meet Lumineux 10% Nano Hydroxyapatite Performance Whitening Toothpaste, a fluoride-free, science-backed formula designed to gently whiten teeth for a healthier, brighter smile. Powered by a clinically supported 10% concentration of nano-hydroxyapatite (n-HA), made from the same minerals teeth are naturally made of, this advanced formula helps replenish lost minerals, visibly smooth enamel, and strengthen teeth with daily brushing. The nano-sized particles work to fill microscopic enamel irregularities and plug exposed dentin tubules, so stains and buildup are less likely to stick while overall tooth smoothness is improved. Unlike harsh whitening toothpastes, Lumineux uses a dual-powered whitening system, whitening by visibly smoothing the tooth surface so light reflects more evenly while also gently lifting surface stains without peroxide, bleaching agents, or enamel-damaging abrasives. The result is a brighter smile that feels clean, smooth, and comfortable. Originally developed by NASA to help protect astronauts' teeth and bones in space, nano hydroxyapatite offers a clinically-studied fluoride-free alternative for modern oral care. Lumineuxs clean formula is safe if swallowed and designed for everyday use, making it ideal for all type of teeth, especially sensitive, and wellness-focused routines. Strong teeth. Gentle whitening. Built on the science of smile longevity.
