Brush head size guide
Pick the correct brush head size based on the user's age, or you can base it on the actual size of the user's mouth. Refer to our size chart to find the best fit.

What is the difference between Fluoride and Nano-HAp?
Fluoride and Nano-Hydroxyapatite (Nano-HAp) both enhance dental health effectively. Fluoride is renowned for its ability to strengthen tooth enamel and prevent cavities. Nano-HAp offers a similar benefit as a fluoride-free alternative, perfect for those who prefer it, and is especially safe for children who might swallow toothpaste.
