Children are suffering an epidemic of damage to their teeth caused by the acid in fizzy drinks and many fruit drinks, say dentists.
Some manufacturers are even adding ingredients that increase the risk of tooth erosion, it is claimed.
Dental experts are demanding changes to the recipes of fizzy drinks to stem 'the increasing prevalence of tooth erosion' among children and teenagers over the last ten to 15 years.
Almost two- thirds of the nation's four to 18-year-olds have tooth damage, which can result in expensive dental repair bills.
One in five children is drinking nearly ten cans of fizzy drinks a week, according to recent figures.
Acids in the products attack the surface of teeth, wearing away enamel and, in extreme cases, eroding them to stumps.
A report in the British Dental Journal today says research shows that fizzy drinks can be successfully modified by adding ingredients that reduce their acidic action on teeth.
The addition of calcium lactate to Coca-Cola, for example, has been shown to 'reduce the erosive potential', but the 'research does not appear to have been taken up by the manufacturer', says the report from the University of Iceland in Reykjavik.
Citric acid was added to Pepsi-Cola and to several carbonated diet drinks.
The report praises the development and marketing of Ribena Tooth Kind, saying extra calcium had made it less erosive than other blackcurrant drinks.
A spokesman for Coca-Cola said it was company policy not to discuss the formulation of its drinks.
A spokesman for Pepsi said: "Along with other soft drinks companies, we use a comparatively small amount of citric acid in some of our products to add a pleasant tartness and bring out the flavour of other ingredients."
