41% of children already getting too much
The Ministry of Health’s MOH Oral Health Survey 2009 found 41% of children in both fluoridated and non-fluoridated areas have some form of dental fluorosis. Other New Zealand studies found 15% in nonfluoridated areas and 30% in fluoridated areas.
Dental fluorosis is caused by an excess of fluoride as the teeth are developing. Most dental fluorosis in New Zealand is very mild or mild although the 2009 Oral Health survey reports 2% of children have moderate dental fluorosis.
As noted by Dr Hardy Limeback (BSc, PhD, DDS) “it is illogical to assume that tooth enamel is the only tissue affected by low daily doses of fluoride ingestion.” According to the late Dr. John Colquhoun, “Common sense should tell us that if a poison circulating in a child’s body can damage the tooth-forming cells, then other harm also is likely.” If a child has a thin blue line on their gum (Burton’s Line) it represents over-exposure to lead or another heavy metal. No one would say it is “only cosmetic”.
