Very sad how some of us are forced to take fluorine in (through drinking and washing)! Glad you paid it some attention. In Anthroposophical health care and medicine it's a big no-no, too. Especially for children! (See below an exerpt from an article on fluorine/fluoride).
However, there are better toothpastes to be made than from coconut oil, since we've all gone too nuts for coconuts recently and the plantations are killing our diverse environment. Furthermore, if you also use the oil in your diet, you are taking in an enormous amount of saturated fats!

Stay healthy and benefit all mankind!
Fluorine and Thinking
In the human being the highest concentration of fluorine is found in dental enamel, the hardest tissue in the body. Dentine limits further tooth development. Essentially this is also a spiritual matter, for the human being is meant to come to a conclusion, i.e. achieve exact definition (finis = end), which gives our thinking its specific quality.
The relationship between the quality of thinking and the condition of the teeth has been known for some time, but is little understood. Thinking can take many forms, but today it is often one-sidedly hardened and intellectual. Other, typically human, qualities such as a sense of mission, achievements in art, morality, wisdom and so forth literally vanish or are considered unimportant and neglected. One-sided development is always a danger and we must be concerned as insidious fluorine enters more and more into all aspects of our life.
Right very sad that many countries accepted to add Fluorine into tap water. We have to spend buying spring fresh water in plastic bottles, which have a bad influence on the body. Thank you for inspiring me through your awesome comments.
