It is designed to help remove plaque and bacteria, and to counteract the acid which that bacteria has produced. Some toothpastes also try to whiten teeth, kill the bacteria, and/or expose the teeth to [[fluoride]]. [[Fluoride]] will try to bond with the calcium in the teeth, thus theoretically making them harder. However, some say that this actually weakens the teeth, perhaps because the [[fluoride]] loosens the calcium's bond to the rest of the tooth. In any case, [[fluoride]] is in plentiful supply, as it is an artificial byproduct of the refining of [[Aluminum]] so it remains a common, cheap substance in many things.
