The UK authorities just lately introduced plans so as to add fluoride to water to chop tooth decay. A invoice is continuing by parliament to help this.
Tooth decay is a quite common illness. In England, it’s the commonest cause for hospitalisation in kids aged six to 10. Tooth decay is attributable to consuming an excessive amount of refined sugar and never brushing enamel sufficient, which results in plaque build-up. It could possibly result in holes within the enamel (caries), dental abscesses and tooth loss. Whereas anybody can expertise tooth decay, it disproportionately impacts folks on low incomes. Tooth decay additionally means practically 40,000 kids require tooth extraction a 12 months – at a value to the NHS of £65 million.
Addressing tooth decay won’t solely imply fewer folks undergo from problems, it would additionally scale back the burden on NHS companies and permit cash to be redirected to different companies. Increasing water fluoridation schemes is one efficient means of doing this.
Stopping tooth decay
Round 25 international locations worldwide already add fluoride to consuming water. Within the UK, 6 million folks have a water provide with fluoride in it – both due to native water fluoridation schemes or as a result of the consuming water of their space naturally incorporates larger ranges of fluoride.
Fluoride is a naturally occurring mineral present in water in various quantities relying on the place you reside. It makes enamel stronger and is proven to cut back tooth decay, which is why it’s usually added to toothpaste and mouthwash. It has additionally been added to consuming water in some components of the UK since 1964. Analysis reveals that as little as 1mg of fluoride per litre of water is required to sort out tooth decay.
Analysis reveals including fluoride to water lowered tooth decay by 28% in five-year-olds residing in disadvantaged communities – making them round 50% much less more likely to must have their enamel eliminated in hospital. In wealthier areas, fluoride in water lowered tooth decay by 17%.

However alongside proposals so as to add fluoride to extra folks’s consuming water, issues have been raised about fluoride’s security – particularly amongst individuals who imagine it might trigger severe hurt, reminiscent of cancers, beginning defects, thyroid issues and neurological injury. Whereas some research have purported to indicate a hyperlink between fluoridation and a variety of harms, these research haven’t held as much as educational scrutiny largely as a result of they haven’t fastidiously taken different components under consideration which will affect the outcomes – reminiscent of smoking, weight problems or age.
There is no such thing as a credible scientific proof that including minimal quantities of fluoride to water could cause most cancers or different ailments. However we do have good proof that fluoride is efficient in decreasing tooth decay and is a protected means to take action. In England, the federal government is required to often report on the well being of individuals residing in fluoridated areas. The latest report on fluoride’s security has once more discovered vital advantages to utilizing fluoride in water – and no proof that it’s unhealthy in your well being.
That stated, fluoride in consuming water (and in toothpaste, if swallowed) might result in mottling (fluorosis) of creating everlasting enamel. That is usually gentle and research carried out in England haven’t proven higher ranges of extreme dental fluorosis in fluoridated areas in contrast with non-fluoridated ones, nor higher ranges of dissatisfaction with dental look. Issues with bone improvement (referred to as skeletal fluorosis) might occur. However that is solely in locations with very excessive pure ranges of fluoride within the water – typically as a lot as ten occasions the degrees seen in fluoridation schemes. Neither of those situations is a priority in international locations the place the extent of fluoride in water is managed.
Over 400 million folks globally drink water containing fluoride together with Canada, Australia, New Zealand and Eire. These international locations don’t report any detrimental results of fluoridation. Within the UK, kids residing in fluoridated areas reminiscent of Birmingham and Newcastle have decrease charges of dental decay and fewer hospital admissions for dental issues.
Tooth decay stays a big burden for folks and the NHS. Including fluoride to water in different components of the UK shall be a protected and efficient means of bettering dental well being for many individuals.
