5 thoughts on “Lack of fluoride in Calgary drinking water leads to rise in kids’ tooth decay, study indicates”
Actually, the rating of this should be POOR. It is the definition of junk science, cherry picking and bias. To say otherwise is indicative of confirmation bias.
Calgary Quiz: Choose the answer for each problem
a) cherry picked data
b) scientific fraud
c) poor study design
d) author bias and scientific advocacy
e) all of the above
Problem 1: Study compares data from 2004/05 to 2013/14 to claim that dental decay increased after fluoridation ended, although fluoridation ended in 2011 and a comparison of data from 2004/05 to 2009/10, the year before fluoridation ended, shows that most of the increased decay was before fluoridation ended.
Problem 2: The number of primary teeth examined in the 2004/05 sample was quite unequal, 599 for Calgary and 6,445 for Edmonton.
Problem 3: Study omits data that showed a decrease of cavities in permanent teeth for the children in the no-fluoride community and instead mentions “non-significant” trend towards increase in a subset of that data.
Problem 4: Study advocates for an optional medical intervention affecting millions, ignoring many larger studies of longer duration with different conclusions as well as multiple studies proving harm.
Problem 5: Study author was a proponent of fluoridation who fought removal. Study featured in near identical articles in multiple Canadian newspapers the day it was published.
The reason there are more cavities are because those kids are drinking more soft drinks and of course, not brushing or flossing much, if at all.
There is no credible evidence that fluoridated water has ever prevented a single dental cavity. The forced-fluoridation fanatics often try to claim that the low rates of dental caries in western European countries which do not have artificially fluoridated public water supplies are due to naturally occurring fluoride in water, or some other kind of artificial fluoridation such as salt fluoridation. They are lying. http://forcedfluoridationfreedomfighters.com/scotland-and-the-netherlands-inconvenient-examples/
Before fluoride was put in the water, my parents gave us fluoride drops when i was growing up. I beleive that that is why I have good teeth today. Same for my siblings. My kids fortunately grew up when fluoride was added to the water supply and they all have good teeth. Now it could be genetics but I doubt that since both of my parents had dental problems. Their parents did not give them fluoride drops so I somewhat discount the genetic factor.
Indeed, regardless of fluoride, refusal to brush one’s teeth will encourage tooth decay.
