Dundee: Mineral water has been found to protect teeth from erosion, says a study at the University of Dundee.
Just two glasses a day offer protection to children from acids even if they continue to drink damaging fizzy drinks.
Erosion caused by carbonated drinks, fruit juices and other foods wear down enamel making teeth sensitive.
The study looked at the lifestyles of 200 youngsters aged 11-13 and the effect on tooth erosion and concluded that the best prevention was fluroid toothpaste.
Dr Graham Chadwick, of Dundee University’s School of Dentistry said that results revealed that minerals in the water offer some protection from acids.
