Acid erosion on teeth caused by too many sugary foods is putting many children in urgent need of dental treatment, according to a new report.
A study by Sensodyne found that 79 per cent of dentists see the effects of acid erosion on young people's teeth every week.
The acid erosion is caused by a number of everyday substances, including fizzy drinks and even fruit.
Experts estimate that nearly one in three 12-year-olds and as many as 53 per cent of five-year-olds are suffering from tooth surface loss.
And the problem could be put down to parents' lack of knowledge about what foods might be causing the problems.
Some 94 per cent of mums and dads said they did not know that acidic foods could cause problems for their children's teeth, while a significant number did not even know what foods are acidic.
Professor Jimmy Steele of the School of Dental Sciences at the University of Newcastle advises: "Adult teeth generally start to appear when children are six years old and need to last a lifetime, so protection from an early age is key.
"Whilst children should not be discouraged from consuming acidic food and drinks, it is important for parents to be aware of the issue to ensure they take small steps to minimise the risk to their children's teeth."
