Children tend to rush tooth brushing and tend to miss areas that are crucial to optimal dental health. It is advised that a parent assist their children when brushing and flossing. As a general rule, when a child can tie their own shoes they will have the required manual dexterity to brush and floss their own teeth. Another reason for assisting children is so that they don’t swallow a large quantity of toothpaste while brushing which can be toxic or lead to dental fluorosis. A pea size drop of toothpaste is the required amount needed for brushing your teeth for an adult and a half a pea size is more than enough for a child.
