Did you know that there is no fluoride in toothpaste in Japan or fluoridation in water distributed in the country? Is this good or bad? Is there really no fluoride in Japanese products and water? In this article, we will talk about some curiosities related to fluoride in Japan.
It seems like a random matter, but it was one of the first observations I had when trying out toothpastes in Japan and realizing that they taste totally different from toothpastes in Brazil. Practically the majority of toothpastes in Japan are composed only of sodium bicarbonate and do not contain fluoride like toothpastes in Brazil.
It does not mean that fluoride is prohibited in the country, it is still possible to find some children’s toothpastes or medicated with a good fluoride composition with some difficulty, but it is not something extremely popular and applied in the Japanese toothpaste market. a low amount of up to 0.8 ppm of fluorine is allowed.
Why does Japan seem to dislike fluoride?
There is a huge controversy surrounding fluoride around 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 was completely disabled.
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 don't show so much aging.
Fluoride can also cause a reduction in bone strength causing osteoporosis. Others report impacts on white blood cells, genetic damage and even cancer. Fluoride can also cause a reduction in IQ and other damage. Of course, for these results it is necessary to consume a lot of fluor. A 70g toothpaste tube is believed to kill a 10kg child.
For those unaware, pure fluoride 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.
Don’t Japanese use fluoride? Is fluoride toothpaste good or not?
This fluor issue looks like a political debate on the internet. Perhaps the lack of fluoride is responsible for the amount of decayed teeth in many Japanese people, although I believe it's just a 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, almost all provinces encourage students to participate in a fluoride mouthwash program. Drinking fluoride water can be harmful, but there are no great risks in using mouthwashes or other methods to prevent cavities.
Although the S-FMR program has been implemented throughout Japan, not all schools or students participate in the process of rinsing their mouths with fluoride. 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 have fluoride. Other research claims that the prevalence of dental caries was high even in communities with a high ppm value in water. That is, the use of fluorine does not really seem so advantageous to the Japanese or any human being.
I really don’t know how to give an opinion or write seriously on this subject. I just wanted to share the conclusion I had when I realized this stark difference in the flavor of toothpaste and water in Japan. What do you think about this? Did you know about this subject?
