Very nice article.

"Prevention of Dental Fluorosis

Dental fluorosis can be limited or prevented by following the ‘recommended limits for fluoride exposure’, suggested by US Environmental Protection Agency (USEPA) [20]. The reference dose suggested by USEPA is 0.06 mg fluoride/kg/ day, which is the estimate of daily exposure that is likely to be without any appreciable risk of deleterious effects (any degrees of dental fluorosis) during a lifetime [20]."

" When the level of fluoride is above 1.5 mg/l (1.5 ppm) in drinking water, dental fluorosis can occur."

". In 2000, approximately 162 million people (65.8% of the population served by public water systems) received water that contained fluoride ranging from 0.7 to 1.2 mg/l (usually 1 mg/l), depending on the local climate."

"Even a small ‘pea-sized’ amount of toothpaste containing 1,450 ppm fluoride, would contain approximately 0.36–0.72 mg fluoride, which if consumed twice a day could contribute to fluoride levels that would increase the risk of dental fluorosis in children [26]. "

(excluding fluoride from other sources)

So a child drinking approx 1.5 L of water per day or brushing teeth twice per day (with inappropriate toothpaste).

Or an average sized adult drinking 4.2L of water per day..

To meet the limits specified in the study above... but hey, let's take Townsville, where some of our more esteemed participants grew up.

Does that not say approx 0.6-0.7mg/L so that would be for an adult 6.5L of water per day.

PS and this is using your favoured fluorosis as the endpoint, hardly that serious especially for the more minor categories (insert response as to the severity of fluorosis according to you (insert response about endocarditis etc by me))
