Fluoride is a naturally occurring substance present in drinking water in varying concentrations. Regulations allow for up to 1.5 milligrams of fluoride per litre of water (1.5mg/l) to be present in drinking water.  It is useful for babies and children, who have growing teeth, and helps reduce tooth decay and cavities.

Regulations allow for up to 1.5 milligrams of fluoride per litre of water (1.5mg/l) to be present in drinking water.

In some areas across the UK, the level of fluoride is adjusted upwards to a target level of 1mg/l in order to improve dental health. At Cambridge Water, we do not adjust the fluoride level in this way.
