Figures from Public Health England show that the cost of fluoridating water supplied to around 6 million people across the country was just over £2 million in 2014/15.

This works out at about 35 pence per person per annum served by those fluoridation schemes and contrasts significantly with the £54 it costs on average to perform of a single filling of decayed tooth on the NHS or the £558 it costs on average to undertake tooth extractions under a general anaesthetic in hospital.
