Fluorosis is the Pits
written by Steven Barrymore
The U.S. Environmental Protection Agency (EPA) has announced that it has reevaluated the current science on fluoride. While the U.S. Department of Health and Human Services (HHS) has proposed an adjustment to the levels of fluoride in drinking water. The current enforceable standard for fluoride is 4.0 mg/L. This may be too much for children’s developing teeth and for adult health.
Excessive fluoride in children 8 years and younger have an increased possibility of developing staining and pits in the tooth enamel. If this damage is excessive it could require dental intervention.
Adults exposed to excessive consumption of fluoride over a lifetime may have increased likelihood of bone fractures, and may result in effects on bone leading to pain and tenderness. source: EPA 2011 Q & A on Fluoride
In 2006 the EPA requested the National Research Council (NRC) to review data on drinking water standards collected by the EPA in 2003. The NRC recommended in their published report to the EPA, ‘Fluoride in Drinking Water: A Scientific Review of EPA’s Standards’, that the EPA update its analysis with new data on health risks and fluoride exposure. The NRC panel also recommended that the EPA update its goal to the public health in the areas of tooth enamel pitting, stage II & III skeletal fluorosis and bone fracture risk.
The EPA will be doing further risk assessment to determine if revised fluoride levels in public drinking water are needed.
The best way to find the fluoride level of your local public water system is to contact your water utility provider for more information, according to the EPA.
Additional sources of fluoride can include toothpaste and mouthwash. You and your children should not swallow these products during their use as they can add to an over-all fluoride intake.
Bottled water products labeled as purified, distilled or de-ionized contain no or trace amounts of fluoride unless they are labeled to contain fluoride. Spring water can contain added or naturally present fluoride (from the original source of the water). The FDA limits the amount of fluoride in bottled water to a range of 0.8 to 2.4 mg/L.
The 1960′s became the era of fluoridation as a widely used practice in public drinking water.
