Teeth with dental fluorosis 
Answers:
Some people disapprove of fluoride since they do not know what it is. Since now knowing what fluoride is and how it can protect your teeth from teeth decay I would put fluoride in my drinking water and tooothpaste. I would never want to get yellow spots on my teeth and fluoride protects that from happening. McKay’s quest to determine the cause of the staining ended three decades later with the discovery that the town’s drinking water had high levels of naturally occurring fluoride. Subsequent research determined that water fluoride levels below 1 ppm prevent decay without the attendant staining. In a trial launched in 1945, Grand Rapids, Mich., became the first city to fluoridate its water; 11 years later, the benefits of the practice were clear and widespread fluoridation began. Further research, culminating in the late 1940’s established that at optimal concentrations, (0.7 to 1.2 parts per million) fluoride in the water supply gave protection against decay without causing the spotted teeth. Some side effects of fluoride is dental fluorosis. It is caused by having too much fluoride when the teeth are developing. This can happen when fluoride supplements are taken by children under 7 who live in areas where the water supply is fluoridated. It can also happen when children swallow toothpaste. Excessive fluoride can cause yellowing of teeth, white spots, and pitting or mottling of enamel. Consequently, the teeth become unsightly.
