Happy Tooth Hydroxyapatite Toothpaste is a 4oz (113 g) fluoride-free formula designed for the whole family. Built around 10% micro-hydroxyapatite, it helps fill micro-lesions in enamel, supporting remineralization and a brighter smile without peroxide or abrasives. Founded by pediatric dentist Dr. Tyler Hanks, it addresses enamel health at the source, not masking sensitivity. Most users report smoother enamel within two to four weeks and visible brightness in six to eight weeks. Suitable for toddlers, kids, and adults, including those with sensitivity or post-ortho concerns. Free from SLS, artificial sweeteners, and flavors. Apply a pea-sized amount twice daily, no rinsing needed. Delivered in 4 days to India via ExpressBox, duties included.
