Dental Did You Know: High Fluoride Toothpaste and Cavity Reduction

The use of high fluoride toothpaste (5000ppm) caused the re-hardening of 76% of non-cavitated root caries lesions. In contrast, toothpastes that had only (1100ppm) caused the re-hardening of only 35% of lesions.

Reduction in fluoride in Edmonton's Public Water Supply

Edmonton, on the advice of Health Canada has reduced the concentration of fluoride in the public water supply to 0.7 ppm (parts per million) from 0.8 ppm based on an expert panel's recommendation. Here's the teaser quote from the Edmonton Sun:

Edmonton-area residents will soon have less fluoride in their tap water, thanks to Health Canada.

Capital Health's Dr. Gerry Predy told Sun Media that he will ask EPCOR, which provides water to the city and surrounding communities, to reduce the maximum amount of the chemical that it adds to the water supply, from 0.8 parts per million to 0.7 ppm.

Dental Did You Know: Tooth Bleaching Using 10% carbamide peroxide and Enamel Hardness

In a recent study, it was shown that bleaching teeth with 10% carbamide peroxide can reduce enamel surface microhardness. It was recommended by the authors to either add professionally administered or self-administered fluoride to remineralize the enamel.

London tap water missing fluoride: C-Health Article

Saw this article in C-health. The fluoridation of London's water supply was quietly shut down September 3rd after the commercial distributor in Canada had run out. What is a bit disturbing to me is the lack of communication from the municipal department to the public regarding the change in their water.

Here's the teaser quote:

For weeks most Londoners have been drinking tap water without fluoride, the result of a continental shortage of the substance that's added to water to prevent tooth decay.

It took a plebiscite in the city 41 years ago to give the go-ahead for fluoridated water, but the equipment to add it was quietly shut down Sept. 3 for the larger of London's two water supply lines.

Asked last night whether Londoners should have been told their water composition had changed, at least one city council member was unprepared to take a position.

Dental did you know: Milk and Teeth

Enhancing milk with fluoride reduced the number of decayed, missing or filled teeth in a 21 month long study. Milk itself contributes to enamel remineralization (healing), prevents bacteria from attaching to teeth and forming biofilms.
