Fluoride side effects - Lady shows healthy teeths


The mineral fluoride would be necessary for healthy teeth, but in pure form, it is also a toxic industrial waste product. So the question is whether fluoride, certainly in high doses, is as healthy for our body and our health, and whether it outweighs the so-called beneficial effect on our teeth.

You can read more about this in this article.

This waste product is released when producing aluminum and phosphate fertilizer. It is a widely used ingredient of toothpaste, mouthwash and other tooth products and in several countries, such as America, Canada, Australia, New Zealand and Brazil, it is even added to the drinking water. In Austria, the Netherlands and Belgium no additional fluoride is added to the water. However, the water naturally contains a small amount of fluoride. In the Netherlands, in 1973, the Supreme Court ruled that the government was not allowed to add fluoride to the drinking water, something the government wanted to prevent tooth decay. The World Health Organization (WHO) states that the teeth of people in countries where fluoride is added to the water nowadays are not stronger, firmer or better protected against holes.

In America, it is then added to the drinking water, but the tablets with fluoride prescribed there for people who do not drink the water, have never been approved by the US Food and Drug Administration (FDA), in fact, the tablets that they have examined have been rejected. Fluoride returned to the news when a major medical journal, The Lancet, wrote last month that six chemicals are now classified as a neurotoxin. In many countries, it’s banned.

These six chemicals, including fluoride, have been added to an existing list of five chemicals from 2006. A neurotoxic substance can damage the brain and other organs under a prolonged load. Neurotoxins can block or strengthen the impulse transfer, which means that the nervous system can partially fall out or become overactive. This involves large quantities. According to research, which once again came to the fore in the publication of The Lancet, these chemicals, including fluoride harmful to the development of the brain, have been demonstrated in children in this study (Dr. Philippe Grandjean and Dr. Philip J Landrigan).

This is not the only study that shows that fluoride may cause brain damage: there are more than 34 studies performed on humans and more than 100 studies that demonstrate this via animals. One of these studies, of Harvard University in 2012, has received a lot of publicity and has been published in ‘Environmental Health Perspectives’ by the National Institute of Environmental Health Sciences. The conclusion of this research (Choi et al.)

States that children living in areas where more fluoride is added to the water have a significantly lower IQ than children living in areas where a lower percentage of fluoride is added to the water. Research from 2011 (Ding) states that water with a lower percentage of fluoride has negative effects on the brain and even the intelligence of children.

Researcher Choi later said about the research: “For us, it is incomprehensible that both children and adults are exposed to a substance that can cause brain damage, under the guise of protection against tooth decay. Does the reduction of tooth decay have more priority than brain health? “Choi and his team also state that fluoride is a substance that reaches an unborn child through the placenta and can already cause damage to the developing brain. Although no additional fluoride is added to our drinking water, these examples say something about the effect of fluoride on our body. Moreover, our drinking water naturally contains a small amount of fluoride.

Maybe you are afraid of this information, but it involves large quantities or years of use that will accumulate in the body. The intention of this article is to raise awareness so that you have more information about a subject and can make your own choices.

Fluoride is good for our teeth?


Enamel Fluorosis accurate photosIt was discovered at a certain point that the teeth of people were harder and stronger in areas where there was more fluoride in the water (even though the extra was not added). When fluoride is absorbed by the tooth enamel, the teeth are more resistant to tooth decay. The favorable effect on tooth enamel is supported by statistics showing that less caries occurs when using fluoride.

Even though there have been later studies that contradict this. Such as research in 2001, published in the International Journal of Pediatric Dentistry, in which children in South Africa who drank water that naturally contained more fluoride (3 ppm) had more problems with tooth decay than the children in areas with water with less fluoride ( from 0.19 to 0.48 ppm, parts per million). The enormous amount of scientific documentation about fluoride shows a multifaceted picture, that is reason enough to be alert and careful with this substance.

It is known that if there is too much fluoride, white and / or brown spots may appear on the teeth that will not go away. Maybe you think now, I do not swallow the toothpaste anyway?

But much of the fluoride in toothpaste is absorbed by the mucous membranes, even if you do not swallow it. Fluoride also accumulates in our body, the body can not break down fluoride, so even though you get a little bit inside every day, after a long time this can possibly affect your physical health because it ultimately involves a higher dose.

Fluoride warning for kidsIn America, it is mandatory to put exactly how much fluoride it contains on the tube of toothpaste, as well as a warning about the dangers of fluoride in high doses for health, but in the Netherlands, this is not necessary. In the Netherlands, as of 2009, there must be a warning text on toothpastes containing fluoride for children up to and including six years. How much fluoride there is in toothpaste is therefore not always clear. The question remains whether fluoride, certainly in high doses, is as healthy for our body and our health, and whether it outweighs the so-called beneficial effect on our teeth.

Does fluoride have side effects?

In addition to the studies that focus on fluoride damage on depression, concentration disorders, the nervous system, the brain, bones and kidneys, a lot of research is being done into the possible link between fluoride and cancer. As early as 1977, a long-term study showed that death rates due to cancer in ten major cities in America where fluoride is added to the water were higher and faster than in ten major cities in America where no fluoride is added to the water. . After correction of, among other things , age.

did you know this about fluoride?

In 2001, the British researcher J. Luke discovered that fluoride can accumulate in the pineal gland and stated that this affects the effect. For example, the pineal gland makes the hormone melatonin from serotonin and thus ensures a good night’s sleep. Serotonin affects your mood, self-confidence, sexual activity and sleep. Funny detail: by (natural) peoples in ancient times the pineal gland was called the third eye because it would have to do with clairvoyance and the French philosopher Descartes called the pineal gland the seat of the soul.

The retired American scientist William Hirzy of American University states that it would be a biological miracle if such a toxic substance as fluoride would have no side effects in the body.

What do we brush our teeth with?

If you want to choose to brush your teeth without fluoride, then in every drugstore and natural store toothpaste without fluoride is for sale. Azadirachta indica, also known as neem, has a strong purifying effect and is antibacterial.

It is scientifically proven that mouthwash on the basis of neem has much less risk of side effects, compared to regular mouthwashes (Anirban Chatterjee, Mini Saluja et al.), But with the same positive characteristics. You can also find toothpaste based on propolis, a substance made by bees that works bactericidal and fungicidal, according to studies (Wells 1976, Cuéllar et al. 1987).

On the internet, you can also find recipes to make your own toothpaste, for example on the basis of organic coconut oil. Regular rinsing (oil pulling) with organic coconut oil and sesame oil is also proven effective against plaque, mouth odor and bacteria in the mouth (2008 and 2009 Asokan S, Emmadi P, et al.). The less factory-based food and sugar, a major culprit for holes, the better for your teeth. Prevention is always better than cure.

Do I have to avoid it now?

Fluoride is a big topic with much to say about, we can not go into all aspects in one article and not all questions that are answered on this subject. The intention of this article is to shine a light on an underexposed subject so that more information is available and there is a choice that you might not have been aware of before.

You certainly do not have to worry about the fluoride you have in your body so far.

Stress is also harmful to your health!

  1. Thank you very much for sharing this piece of valuable information. I never know that fluoride can be harmful the to the brain and nerve system. All these while I only know this content is available in many toothbrush and perceived as a good addition. I’ve been using fluoride added toothpaste for almost 40 years. Is there any product that can diminish the side effect that caused by fluoride? 

    1. Dear Florence, no the body can’t break down fluoride, but in most cases we should have not get in to much in our system. I also assume you don’t swallow when brush your teeth, but you will spit it out. I just want to bring awareness regarding fluoride and we not really need it for cleaning or teeths. There are better options.


  2. Dear Tommy Diependaal,

    Thanks a lot for sharing and raising awareness about fluoride and I learned a lot of valuable information from this great post.

    Wow, thanks for the recommendation “Neem, has a strong purifying effect and is antibacterial.”

    I am from India, our ancestors used Neem to brush their teeth. We have a old saying “If we lose our teeth we will lose our words”. After reading your post bit afraid and felt it’s better to create our own tooth paste as you suggested or to use Neem.

    Very helpful post!

    1. Dear Paul, there are indeed many ways to make a good natural toothpaste yourself and there are now also enough options to buy a good natural toothpaste. 

      Thanks for reading and comment on my post


  3. Thank you for this enlightening article in regards to fluoride. Every dentist would tell you that fluoride is good for the teeth as it makes them stronger and less susceptible to decay. And that is why when people shop for toothpastes, they always pick those with fluoride. Upon knowing the possible toxic side effects of fluoride, I don’t think people would still want to purchase toothpastes that contain them. This is scary, considering also that it can potentially cause brain damage. Of course, protecting your brain is more important than reducing tooth decay. By the way, you mentioned that it would require large quantities of use, which means more years of use, before fluoride eventually accumulates in the body to potentially cause toxic side effects. So how many years do you think is many years? And are there actually scientific studies done on real people on the toxic effects of fluoride? Or has anyone been reported to have suffered from brain damage as a result of prolonged use of fluoride toothpastes? 

    1. Hi Alice, yes there are about 34 studies done on real people and one of these studies, of Harvard University in 2012. By the way it’s not only from fluoride in toothpaste, but also fluoride use in drinking water. On the moment there is no hard proof that we have to much fluoride accumulate in our body over time. It’s just a choice to consider. And yes there are studies that proof that children had less develop brains when there was to much fluoride using involved.
