Fluoride in Water Does Not Lower Intelligence

An interesting article titled “Community Water Fluoridation and Intelligence: Prospective Study in New Zealand,” appears in the 2014 edition of the American Journal of Public Health by Jonathan M. Broadbent and et. al. The researchers set out to explore whether or not having fluoride in water that one drinks when they are young and age effects the developing brain negatively. The researchers followed nearly all aspects of the health and development of around 1,000 people born in Dunedin in southeast New Zealand in 1972-1973, up to age 38. The researchers compared IQs of those who grew up in Dunedin suburbs with and without fluoridated water. Furthermore, if one used fluoride toothpaste and tablets the researchers used this in their analysis. The researchers focused on fluoride expose during the first five years of life as this is a critical period of time … Read more

Large Amounts of Fluoride Consumed by Young Children Leads to Fluorosis

A recent study looked at the role of fluoride in young children. It was found that young children who consume large amounts of fluoride through fluoridated water and beverages mixed with flouridated water as well as by swallowing toothpaste with fluoride have an increased chance of developing mild enamel fluorosis. The study noted that all of the fluorosis in the young children seen was mild and that they feel that the oral health of these young children was not adversely affected in anyway. If a child has mild enamel fluorosis there will be barely noticeable faint white lines or streaks on tooth enamel. The researchers used mothers of newborns from eight Iowa hospital postpartum wards between 1992 and 1995 which is known as the Iowa Fluoride Study. A total of 630 children were used in the study and questionnaires were … Read more
