went to the dentist today. he suggested fluoride, even though I promptly said I don´t use it. there is "no proof that fluoride is harmful", except what I just found :
Beyond this ethical dilemma and the aesthetic issue of fluorosis (teeth mottling), there are a number of other reasonable medical objections to water fluoridation. These include: that the doses of fluoride individuals receive cannot be controlled, and go to everyone using the water supply, regardless of their age or state of health; that fluoride accumulates in the body over time, especially in the bones and the pineal gland in the brain (which regulates the release of some hormones, including melatonin); that fluoride can affect the functioning of the thyroid gland; there is also some academic research to suggest that fluoride may damage the brain and lower IQ levels; fluoride has also been linked to occurrences of bone damage, arthritis and cancer.
found in this article, that is really a covert ad for mints. : https://www.telegraph.co.uk/health-fitness/body/common-sense-guide-fluoride-great-dental-conspiracy-magnet/
it´s about the dangers of water fluoridation, however, at clearly states that traces of fluoride is not something I want in my body and pineal gland.
btw no holes in 7 years, and no fluoride toothpaste for several years............
