Smile+ is the world's first teeth whitening pouch. A new way to whiten, freshen, and rebuild during the 16 hours a day you can't brush. Each pouch contains 55mg of nano-hydroxyapatite which bonds to your enamel, supports remineralization and helps to lift surface stains from coffee, tea, and daily life while supporting enamel strength. A gentle daily whitening option even for sensitive teeth. The Oral Defense Matrix combines eight purposeful ingredients including xylitol, zinc citrate, papain enzyme, soluble calcium, and aloe vera to neutralize acids, freshen breath, and support oral health. Caffeine free, nicotine free, and sugar free. Simply place a pouch between your cheek and gum for 20–40 minutes, 1–3 times daily. Mint Ice flavor, 15 pouches per tin.
