Effects of fluoride: Does fluoride affect the thyroid?
I have heard that fluoride in toothpaste and water adversely affects the function of the thyroid. Do you think there is any truth in this?
Dr Fred Kavalier answers your health question:
Fluoride in high doses can effect the functioning of the thyroid gland, but the amount of fluoride in water and toothpaste will not have any significant effect. In 2000 a review of the scientific literature on water fluoridation was carried out by the NHS Centre for Reviews and Dissemination at York University. They concluded that there was no reputable scientific evidence to support the idea that water fluoridation caused thyroid problems. Too much fluoride can cause a discolouration of the tooth enamel – dental fluorosis – but unless you are ingesting excessive amounts of fluoride, I would not worry about your thyroid gland.
