In the last week water fluoridation has made the headlines again, alongside the continuing articles and posts related to SARS-Cov-2 and the rollout of vaccines against it. One of the common features shown by quite a few of those opposed to these 2 public health initiatives (fluoridation & vaccination) is a tendency to claim that those supporting the initiatives in … Read More

The latest NZ school dental service data again confirms that community water fluoridation is effective. The data show benefits of up to about 30% improvement in oral health. But, anti-fluoride activists will, once again, reject this evidence and instead cherry-pick the data to support their claims. The NZ Ministry of Health (MoH) has posted the latest summary of child dental … Read More

Stopping community water fluoridation in Alaska’s capital city, Juneau, caused an increase in child tooth decay In the last week, Windsor in Ontario, Canada, voted to reinstate community water fluoridation (CWF) 5 years after it was stopped because of opposition. This time the City Council was swayed by the Windsor-Essex County Health Unit’s Oral Health 2018 Report which found the percentage … Read More

A group of well-known anti-fluoride activists have just published some new research. Well, this is what their social media publicity will tell us. In fact, this is not new research. It is simply the republication of a shonky paper from two years ago as a chapter in a book produced by a predatory open access publisher. It is a clear example … Read More

A new high-quality study of the effect of fluoride on the memory and learning behaviour of rats has produced definitive results. Anti-fluoride campaigners had great hopes this study would bring an end to community water fluoridation (CWF) – but their hopes have been dashed. The study showed no effect of fluoride on the memory, learning and motor skills of rats thus reinforcing the consensus … Read More

Data from Bashash et al., (2017). Despite a statistically significant relationship of child IQ with mothers prenatal urinary fluoride, this explains only about 3% of the huge scatter in the data. I haven’t followed the latest speaking tour of Paul Connett – organised by the local Fluoride Free NZ organisation. But I watched a TV interview with him this … Read More

Anti-fluoride campaigners often promote dental health programmes which they argue are alternatives to community water fluoridation. But seem not to understand that these programmes usually include fluoride dental treatments. It’s probably a result of some tactical thinking – “let’s promote a positive message to overcome the publicly perceived negativity associated with our opposition to a social health policy like fluoridation.” In fact, some New Zealand … Read More

It seems every time anti-fluoride propagandists present data it is either cherry-picked, distorted or misleading. Often all three. So it is hardly a surprise to find local anti-fluoride propagandists are telling porkies again. They have been promoting this graphic claiming it shows people in “non-fluoridated Christchurch have “better teeth.” But the graphic is based on naive cherry-picking of the data, it ignores the effect different ethnic … Read More

A new Australian study confirms that lifetime access to community water fluoridation (CWF) is associated with reduced tooth decay for adults – at least in the age groups 15 – 34 years and 35 – 44 years. The study is reported in the paper: Do et al., (2017). Effectiveness of water fluoridation in the prevention of dental caries across … Read More

Anti-fluoridation activists are soon likely to be promoting a new paper reporting a study which found a relationship between maternal (in utero) exposure to fluoride and cognitive development delay in infants. Could the increased incidence of premature births explain cognitive deficits observed in areas of endemic fluorosis? Image credit: New Kids-Center. Of course, they will be unlikely … Read More
