Effective enamel remineralization support.
Fluoride-free for safer use.

Main Highlights

10(nHp): Our unique formulation includes a potent 10% Nano-Hydroxyapatite for proven enamel remineralization, and it's gentle on young teeth and gums thanks to xylitol with a low abrasiveness (RDA 38). Encourage your kids to use it twice daily for a smile that's both healthy and fun. Elevate their oral care with science-backed excellence, specially crafted for little ones!
Xylitol Toothpaste: Xylitol disrupts the growth of bacteria in the mouth, particularly Streptococcus mutans, which is a primary culprit in tooth decay. These bacteria feed on sugars from the food we eat and produce acids that erode tooth enamel, leading to cavities. However, when exposed to Xylitol, these bacteria are unable to metabolize it effectively, reducing their ability to cause harm to the teeth.
Sensitive Toothpaste: the inclusion of aqua (water) and glycerin derived from coconut in toothpaste contributes to its effectiveness in cleaning and protecting the teeth and gums, while also providing a pleasant texture and flavor during use.
Remineralizing Toothpaste: Calendula extract is obtained by extracting the beneficial compounds from the petals of the calendula flower. This Proven ingredient is often preferred in toothpaste formulations due to its gentle nature and effectiveness in promoting gum health.
Fluoride-Free: While fluoride is beneficial for preventing tooth decay in adults, excessive fluoride intake in children can lead to dental fluorosis, a condition characterized by discoloration and mottling of the teeth. PureSmile Kids is fluoride-free, providing a safe option for young children who may be at risk of ingesting toothpaste.
