China does not fluoridate. Why not write an article supportimg fluoridation of China’s water? After all, the USA already has many options for fluoride intake: dental visits, crest toothpaste. Why are you in another country, advocating for mass drugging of an entire water supply, whether the people want it or not? You address scientific studies showing that fluoride can prevent tooth decay, but you don’t address whether it is ethical to drug a populace against their own will. Sorry Dr. Leung, but anyone that is still advocating for massive drugging of any populace needs to be questioned, their motives.
