“Also, soy-based formulas are consistently higher in fluoride content than milk-based products. Other foods that have high fluoride content are teas, dry infant cereals and processed chicken, fish and seafood products,” says Ismail.
“It should also be emphasized that “topical” fluorides such as toothpaste can also have a systemic effect if inadvertently swallowed by young children,” cautions Dr. Ismail. Fluoride also gets absorbed into the bloodstream even when not swallowed.
"Tooth mottling should be monitored in communities to assess fluoride intake and recommendations made accordingly,” writes Ismail.
However, few communities follow Dr. Ismail's advice and fluoridate the water without considering residents’ total fluoride intake from other sources. In fact, a Connersville, Indiana, study indicated children already ingested too much fluoride; but dentists lobbied successfully for fluoridation anyway. To our knowledge, no dental fluorosis studies have ever been published on this population.
Dr. Ismail questions whether mild fluorosis is acceptable any more with esthetics becoming more important in this day and age. He says, “decisions concerning this tradeoff could warrant reconsideration. Fluorosis varies in appearance from small white striations to stained pitting and severe brown mottling of enamel,” he writes.
“The main documented risk factors for fluorosis (in no particular order) are fluoride in water, infant formula reconstituted with fluoridated water, supplements and dentifrices,” he writes.
Dr. Ismail reports that “Commissioned by the EPA, a 2006 National Research Council (NRC) study has sparked the latest controversy. In addition to unsightly enamel fluorosis at 4 ppm and above, it claims: a possible increased risk of bone fracture in certain conditions; skeletal fluorosis; and potential to cause bone cancer...”
“Fluoride is incorporated into bone...after a point though it can make bone more brittle and at higher levels can cause “skeletal” fluorosis, which has a greater potential for painful joints and even fractures,” reports Ismail.
“The over use of fluoride during the first six to eight years of life represents the important period of tooth development when enamel fluorosis can occur. It is critical for parents to monitor fluoride sources to reduce the occurrence of white spots from fluorosis,” he writes.
The Centers for Disease Control reports that 60% of adolescents now suffer with dental fluorosis – 3% of it is moderate or severe. At the same time tooth decay rates are increasing in toddlers and untreated tooth decay has become epidemic.
In Kentucky, despite a 1977 fluoridation state-wide mandate, preschoolers cavity rates went from 28% in 1987 to 47% in 2001, according to the July/August 2003 journal, Pediatric Dentistry,
It’s not just Kentucky, tooth decay went up after fluoridation began in San Antonio, Texas, also.
Last week, KENS 5 – TV reported “After 9 years and $3 million of adding fluoride, research shows tooth decay hasn’t dropped among the poorest of Bexar County’s children. It has only increased—up 13% in 2010, the latest date that data was available.
One out of two children in the Head Start program who were checked for cavities had some decay last year.”
Actually tooth decay crises are occurring in all fluoridated cities, states and countries.
Fluoride Supplements Just as Useless
Dr. Ismail reported "There is weak and inconsistent evidence that the use of fluoride supplements prevents dental caries [cavities] in primary teeth," according to a systematic review of fluoride supplement research published in the November 2008 Journal of the American Dental Association. Dr. Ismail is also an organizer of the American Dental Association Clinical Recommendation Panels on Fluoride Supplement.
“This review confirmed that, in non-fluoridated communities, the use of fluoride supplements during the first 6 years of life is associated with a significant increase in the risk of developing dental fluorosis, write researchers Ismail&Bandekar and first published in Community Dentistry and Oral Epidemiology, February 1999 and to the ADA's website July 2007 but then taken down.
The FDA never safety tested nor approved fluoride supplements for use in children or adults.(4)
