York Health Economics Consortium study says water fluoridation is the most cost-effective way of reducing tooth decay
A 1994 study by the University of York Health Economics Consortium concluded that water fluoridation is the most cost-effective policy for reducing tooth decay.
Following a more detailed examination of the cost and benefits, the York Consortium published a further report in 1998. Key findings were:
Studies comparing the cost-effectiveness of water fluoridation with that of other strategies for reducing tooth decay always conclude that water fluoridation is the most cost-effective approach.
One of the greatest strengths of water fluoridation is that it does not require any behavioural changes from its recipients.
As the size of the population served by the fluoridation plant at a particular water treatment works increases, the cost per person of fluoridation decreases. The larger the population served, therefore, the more cost-effective fluoridation becomes.
