Mr Evans said the warnings from health authorities back in the early 1990s when Tauranga's fluoride debate was raging had not happened.
The statistics showed that children in non-fluoridated areas had better teeth for 13 of the 20 sets of statistics.
The claims by the pro-fluoride people, including the Ministry of Health have proven to be without foundation, he said.
"In fact children's teeth without fluoride in their water supply are as good as the fluoridated areas and in many cases better," Mr Evans said.
There was a link between parenting and tooth decay. "Poor parenting produces poor teeth and fluoride won't save them," he said.
The Waikato/Bay of Plenty president of the New Zealand dental association John Twaddle said a national survey carried out in 2009 conclusively proved the health of people's mouths was 20 per cent better in most age groups in fluoridated areas than non-fluoridated areas.
He said there were epidemics of decay in non-fluoridated towns such as Opotiki and Kawerau, whereas the health of children's teeth had improved amazingly since he started dentistry in Whakatane, a few years after the town put fluoride in its water.
Tauranga dentist Graeme Lynan and member of the New Zealand Dental Council said dentists still supported fluoride in water supplies because of the way water washed over all teeth and was effective even with people who had poor dental hygiene.
