Research shows that although fluoride toothpaste can be effective prevention and treatment of dental caries, excessive using can lead to an abnormal condition. Experts advise the use of fluoride toothpaste every time when it is best not to over 1 cm ,while children are often unable to control the correct amount of toothpaste without adults’ guidance. Now, with the scale of the toothbrush you can safely let kids squeeze the toothpaste by themselves. How long is 1CM? The toothbrush will tell you.
