The Brewing Controversy Over Fluoride in Drinking Water

WILLIAMSPORT, COLLEGEVILLE AND PHILADELPHIA, PA – There is a controversy brewing over fluoride. While it is known to protect your teeth from cavities, a growing number of studies call into question the safety of fluoride in drinking water, due to the potential health risks caused by ingesting it.

Documents recently made public as a result of the Freedom of Information Act show that since the 1970s, the dental health professionals at the Centers for Disease Control have entirely controlled the agency’s stance supporting water fluoridation.  No toxicologists, diabetes experts, minority health professionals, or professionals outside the Oral Health Division had any input into the agency’s position, according to information released by the Fluoride Action Network in June.
The obtained documents have drawn attention to the CDC’s and EPA’s fluoride safety statements, which appear to be at odds with a wide array of current scientific knowledge.
According to the Fluoride Action Network,  law firms have begun looking at documents that are believed to shine a spotlight on a pattern of attempts to thwart discussions on fluoride toxicity and downplay the importance of professionals personally reviewing scientific reports about fluorides.
Studies suggest that ingesting fluoride could lead to cancer and contribute to the early onset of Alzheimer’s Disease.

“There is a great deal of published research out there which shows that minorities, kidney patients, people with diabetes, babies and senior citizens are particularly at risk for harm from ingested fluorides,” says Philadelphia periodontics expert Dr. David DiGiallorenzo. “I am of the opinion that fluoride in drinking water is of no therapeutic use and is toxic.”

A 1994 scientific study published by the New York Times showed that aluminum and fluoride in water could be the culprit behind an increase in Alzheimer’s Disease and dementia, according to an article posted on

Some countries, including  Sweden, Norway, Denmark, Germany, Italy, Belgium, Austria, France, and The Netherlands, to name a few, have banned fluoride from community water supplies, according to a January 2008 article written by Dr. Ted Spence, a dentist. The United States still seeks to fluoridate every community water supply in the country.

George Glasser, an environmental writer, has seen numerous studies that verified that fluoride can act synergistically with other toxic minerals in drinking water. He urged the U.S. government for years to research this possibility, according to the Mercola article. Twelve years ago, the U.S. Environmental Protection Agency reviewed three studies that had been conducted by scientists at Binghamton University in New York. The scientists reported 80 percent death rates, kidney damage and brain damage in rats that were exposed to half of one milligram of aluminum fluoride complexes in one liter of drinking water. This amount is less than half of the amount of fluoride that gets added in fluoridation projects.

The National Toxicology Program was requested to commission studies to measure the extent of neurotoxic damage caused by aluminum in drinking water, and stressed the fluoride interaction in particular, Glasser said.

In October 2000, a National Institutes of Environmental Heath Sciences report acknowledged that fluoride has been observed to have synergistic effects on the toxicity of aluminum. Additionally, the report found that a majority of drinking water possesses a significant level of fluoro-aluminium complexes. Most water treatment processes result in higher levels of aluminum in the finished drinking water, the report stated.

“This is alarming, given the fact that many, many dentists believe that fluoride simply helps prevent cavities and is safe when added into the water supply,” says DiGiallorenzo, a metal-free implant dentist. DiGiallorenzo, an expert in treating periodontal diseases with LANAP, said he intends to keep an eye on the issue.
“It will be quite interesting to see what shakes out,” he says. “In the mean time, I don’t recommend drinking water with fluoride in it.”
