Compared to children in Edmonton, Calgary’s children are consuming less sugary drinks, are brushing and flossing their teeth more often; and are more likely to have seen a dentist, to have had professional fluoride treatments, and to have received topical fluoride rinses. Despite all of this, Calgary’s children are experiencing more dental decay than Edmonton’s children.
The science is clear. After conducting a study of 5,249 Grade 2 school children some 7-8 years after fluoridation was undemocratically removed by Calgary City Council -- a study from the University of Calgary has shown, once again, that the elimination of fluoridation has caused damage to Calgary’s children.
- Since Dr. McLaren’s 2016 study (“Study shows tooth decay worsened in Calgary children after fluoride removal”), the dental decay gap has only widened between Calgary and Edmonton children.
- Where children lived also had an impact: 56.4% of children who lived their lives in Calgary had at least one cavity on one smooth surface of their teeth, versus 40.8% who had lived their whole life in Edmonton.
- Fluoridation had inconsequential and minimal side effects. The researchers found that some cases of a cosmetic effect on the teeth but stated that “it is important to note that nearly all cases (>99%) in both cities were mild, which is in line with national estimates.” The benefits of fluoridation in the prevention of dental decay clearly outweigh the minimal prevalence of mild dental fluorosis.
The researchers conclude with the following:
“Our findings are consistent with an adverse impact of fluoridation cessation on children's dental health in Calgary and point to the need for universal, publicly funded prevention activities—including but not limited to fluoridation.”
