Fluoride levels fine: Report

COF-COF News Find 300 x 300By: Mississauga News, Brampton, Ontario 16-November-2011 – A report set to go before municipal council in January is recommending Peel stick with current fluoride levels in the water supply, despite growing concerns that fluoride, used mainly to prevent tooth decay, may pose a health risk.
Peel Health has looked into possibly reducing the amount of fluoride in drinking water from 0.7 mg/L (milligrams per litre) to 0.2 mg/L, or the minimum amount recommended by the province and federal government.
The report is in response to Regional Council’s request from a meeting in April that staff research the feasibility of reducing fluoride in drinking water.
At that meeting, councillors heard from some 20 delegates on both sides of the fluoride debate.
Among the advocates speaking in favour of fluoride was Ontario Chief Medical Officer of Health Arlene King, who stressed the importance of fluoride for good oral health.
Advocates support the use of fluoride because they argue it makes teeth stronger and helps to reduce the rate of decay, which is particularly beneficial for children in poorer areas who do not have access to regular dental treatment.
However, delegates speaking against the practice, comprised mainly of Peel residents, pointed to evidence they believe shows a link between exposure to fluoride in drinking water and several adverse health affects including dental fluorosis — caused by excessive ingestion of fluoride during the tooth forming years— gene mutation and cancer. They called on the Region to stop adding fluoride to the water supply.
The group is part of a growing chorus of critics across North America arguing water fluoridation poses ethical and health problems.
In the end, councillors opted to stick with fluoridation — a process that has been used in Peel for some 40 years — but not before asking staff to dig a little deeper into the matter.
Staff largely drew on comprehensive reviews Health Canada did between 2007 and 2010 which reaffirmed the agency’s guideline of 0.7 mg/L fluoride concentration in the drinking water supply.
This “optimal level” (between 0.5 and 0.8 mg/L) is necessary to provide the desired protection from dental decay for a population, according to the research.
“Given the extensive review and the current recommendation of 0.7 mg/L, lowering fluoride in drinking water to 0.2 mg/L would not be effective in decreasing tooth decay,” the report to Council states.
But the report does point to the need to better educate the public about proper use of fluoridated toothpaste, especially for young children. The concern is children that use too much toothpaste could cause fluorosis.
Although governments and industry recommend how much toothpaste people should use, the local public health unit says not enough is done to instill proper practice.
Peel Public Health wants to advocate to Health Canada and the Concerned Children’s Advertisers to more accurately depict appropriate amounts of toothpaste in advertising.

Peel fluoride debate

COF-COF News Find 300 x 300By: Brampton Guardian, Brampton, Ontario 28-Apr-2011 – Peel Region’s drinking water will continue to be fluoridated after council decided today to carry on with the 40-year practice. Councillors opted to stick with fluoridation after hearing arguments from more than 20 delegates representing both sides of the fluoride debate.
Delegates speaking against the practice, comprised mainly of Peel residents, pointed to evidence they believe shows a link between exposure to fluoride in drinking water and several adverse health affects including dental fluorosis — caused by excessive ingestion of fluoride during the tooth forming years— gene mutation and cancer.
The group has added its voice to a growing chorus of critics across North America arguing water fluoridation presents several ethical issues and can be linked to serious health problems. “We are counting on you to make the right decision,” said Mississauga’s Liesa Cianchino during Thursday’s meeting. “Get all the facts and remove fluoridated water.”
Among the advocates speaking in favour of fluoride was Ontario Chief Medical Officer of Health Arlene King, who stressed the importance of fluoride for good oral health.
Advocates support the use of fluoride because they argue it makes teeth stronger and helps to reduce the rate of decay, which is particularly beneficial for children in poorer areas who do not have access to regular dental treatment.
“The value of drinking water fluoridation should not be underestimated,” King said. “As tooth decay is the single-most common chronic disease among Canadians of all ages, and as poor oral health is linked to diabetes, heart disease and respiratory conditions, water fluoridation is an extremely important health measure. In fact, water fluoridation has been called one of the greatest public health achievements of the 20th Century.”
King, who left council chambers immediately after her speech, was followed by a long list of dentists and other health professionals arguing in support of keeping the status quo.
Dr. Paul Andrews, assistant professor in the department of paediatric dentistry at the University of Toronto, said fluoride has significantly cut the rate of tooth decay.
“It is the most effective way to reduce tooth decay. It is categorically safe,” Andrews said.
Fluoride is found in all fresh water supplies and in oceans.
People are exposed to fluoride at various levels in natural drinking water sources everyday.
Opposition to fluoridation of drinking water has existed since it was first introduced in the United States in the 1940s.
During the 1950s and 1960s, some opponents of water fluoridation suggested that fluoridation was a communist plot to undermine public health.
Peel introduced fluoride into the municipal drinking water system in the late 1960s for the prevention of tooth decay.
Fluoride levels are maintained at 0.5 to 0.8 milligrams per litre as stipulated under legislation.
It costs Peel $400,000 a year to add fluoride to the water.
A number of municipal councils in Canada, most recently Calgary, have opted to discontinue fluoride in municipal water.
Delegates today urged Peel Region to follow suit.
They claimed there is no proof that fluoridated water supplies influence oral health in a positive way.
The group presented a mountain of facts gathered from various studies  and other sources that they said point to fluoride as being extremely hazardous.
Carole Clinch, a resident of Waterloo, said combined with fluoride found in other sources, particularly toothpaste, the amount of fluoride people ingest is unsafe.
In the end, council decided to keep on with water fluoridation.
Dr. David Mowat, Peel’s medical officer of health, said water fluoridation has been well-studied to weigh both its benefits and potential health risks.
