Children’s toothpaste or try to choose fluoride free is better. Because the swallowing function of children is not perfect, if toothpaste is accidentally swallowed into the mouth, it may cause the fluoride content to exceed the standard over time, which will affect the development of bones and teeth. Adults can use fluoride toothpaste because their swallowing function is already perfect and they will not swallow the ingredients of toothpaste and affect their health. The ingredients of toothpaste for children can be absorbed by the body without any harm to the body. Therefore, it is not better to use fluoride toothpaste in childhood, but rather to use some toothpaste that does not contain fluoride, and children must use their own special children’s toothbrush. Because adult toothbrushes have larger heads, which can easily cause trauma to children’s gums.
