Fluoridated communities include Newcastle upon Tyne, Gateshead, Wallsend, North Shields, Tynemouth and Whitley Bay.
Derbyshire About 43,000 people are supplied with artificially fluoridated water in Derbyshire.
In these communities, the naturally occurring fluoride is too low to protect teeth from decay and has therefore been supplemented at the water treatment works to bring it up to the 1 ppm concentration.
Some areas receive water with naturally occurring levels of fluoride that is below the optimum for oral health but can afford some degree of protection against tooth decay.
The number of people whose water supplies contain naturally occurring fluoride at the optimum level (around one part of fluoride per million parts of water) is estimated at around 330,000, including those living in Hartlepool and Easington in the north east of England, Uttoxeter in Staffordshire and parts of north Hampshire and south Berkshire.
Around 5.8 million people in different parts of England are supplied with artificially fluoridated water.
This represents 74% of the US population whose homes are connected to public water supply systems.Of the 204 million people receiving optimally fluoridated water, 194 million are served by artificial water fluoridation schemes, an increase of around 8.5 million people since 2008, 20.5 million since 2006 and 32.5 million since 2002.Communities covered by those agreements include Workington, Maryport, Aspatria, Wigton and Cockermouth in the Allerdale Borough Council area and the communities of Whitehaven, Egremont and Ravenglass in the Copeland Borough Council area.Cheshire Around 137,000 people are supplied with artificially fluoridated water in Cheshire.
