Fluoride containing toothpaste is of great benefit to our body, but excessive use will have a negative impact, especially for children. After a health survey found, the healthiest adults using weight: 0.5 grams each, each child 0.2-0.4 G. So I designed this product can not only put the toothpaste to clean, but also through the button on the extrusion rate limiting control, you will never have to worry about the problem of excessive use of toothpaste, moreover it let your health 1+1.
