Did you know that there is no fluoride in toothpastes in Japan and no fluoridation in the water distributed in the country? Is this good or bad? Is there really no fluoride in Japanese products and water? In this article, we are going to talk about some facts related to fluoride in Japan.
It seems like a random subject, but it was one of the first observations I had when trying Japanese toothpastes and realizing that they taste totally different from Brazilian toothpastes. Virtually most toothpastes in Japan are made up of only sodium bicarbonate and do not contain fluoride like toothpastes in Brazil.
It does not mean that fluoride is banned in the country, it is still possible to find some children's or medicated toothpastes with a good composition of fluoride with some difficulty, but it is not something extremely popular and applied in the toothpaste market in Japan. In water, a low amount of up to 0.8 ppm of fluoride is allowed.
Why does Japan seem to dislike fluoride?
There is a great controversy surrounding fluoride all over the world, it is placed in water and toothpastes to prevent cavities, but some studies prove that fluoride is actually unnecessary and can actually be harmful to human health. Until 1972, fluoridation (putting fluoride in water) was practiced by several provinces but it was completely deactivated.
More than 90% countries have drastically reduced fluoride or sometimes completely banned its composition in water, they claim that this is a poison that can even kill. Although the effects are not always visible, some studies claim that fluoride contributes to aging. Perhaps the fact that there is no fluoride in water or toothpaste is one of the reasons why the Japanese do not show so much aging.
Fluoride can also cause reduced bone strength causing osteoporosis. Others report impacts on white blood cells, genetic damage and even cancer. Fluoride can also cause even lower IQ and other damage. Of course, for these results it is necessary to consume a lot of fluor. It is believed that a 70g tube of toothpaste can kill a 10kg child.
For those unaware, pure fluorine is a highly corrosive yellow gas used to kill microbes, but it can also affect our cells. It is so corrosive that it can be used to corrode steel, glass, iron and aluminum.
Japanese don't use fluoride? Is fluoride toothpaste good or not?
This fluoride issue sounds like a political debate on the internet. Perhaps the lack of fluoride is responsible for the amount of rotten teeth in many Japanese, although I believe it is just the person's negligence to go to the dentist. Unfortunately, the Japanese health plan does not include dental plans, and the Dentist appointments are very expensive..
Although there is no fluoride in Japan's water, nearly all prefectures encourage students to participate in a fluoride mouthwash program. Consumption of fluoridated water can be harmful, but there are no major risks in using mouthwashes or other methods to prevent cavities.
Although the S-FMR program has been implemented across Japan, not all schools or students participate in the fluoride mouthwash process. The number of participating schools is close to 10% and few students participate in this incentive.
Only 10% of toothpaste in Japan is believed to contain fluoride. Other research states that the prevalence of dental caries was high even in communities with a high value of ppm in the water. In other words, really the use of fluoride doesn't really seem that advantageous for the Japanese or any human being.
I really don't know how to give an opinion or seriously write about this subject. I just wanted to share the conclusion I came to when I noticed this stark difference in the taste of toothpaste and water in Japan. What do you think about this matter? Did you know about this subject?
