Recent research reveals that community water fluoridation benefits adults as well as children. While research into the effects of fluoridation in adults started earlier than for children, early studies suffered from a lack of information on effects of socioeconomic status and other confounding factors. Recent studies with adults have been more robust but there is still some confusion – especially since … 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

Fluoride is not the only factor in oral health. But it is generally the only element in drinking water considered for its effect on our teeth. Drinking water fluoride benefits existing teeth by chemically reacting with the tooth surface. Involvement of fluoride in the apatite structure at the tooth surface helps prevent demineralisation, due to acid attack, and also encourages remineralisation – … Read More

Seems some prominent campaigners against fluoridation must advocate the stork theory, or something similar, to explain where teeth come from. Apparently they do not understand that teeth develop in the jaw before eruption. Here’s a Twitter message from the “Girl … Continue reading → … Read More

Water fluoridation is flavour of the month again for anti-science conspiracy theorists who consider it mass-medication or in the case of Rusty Kage, sorry Kane, mass poisoning. Anyone for a root canal? Rusty? Source: Taranaki Daily News The US Centre for Disease Control ranks fluoridation of water number 9 on its … Read More
