According to experts, kids should not brush their after every meal because they could be doing more harm than good.

As acid present in food and drink make tooth enamel supple, using a toothbrush immediately after meal can scratch the surface and wear it down.

According to a poll, 79% of dental professionals see acid erosion on kids’ teeth at least once a week than ever before.

Eating foods having high acid content like fruit juice, fizzy drinks and some sauces, can cause erosion.

The study of British dentists and parents of school-age children, by toothpaste company Sensodyne, discovered that around 53% of five-year-olds exhibit some type of acid erosion, which is caused by acid in food and drink rotting away the enamel of the tooth.

Prof. Jimmy Steele of the School of Dental Sciences at The University of Newcastle, who analysed the study results, stated that kids should avoid brushing instantly after having acidic food or drinks as this is when the enamel is at its softest.

Steele said, “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.”

“Encourage them to drink acid drinks with a straw placed towards the back of the mouth away from teeth.”

“And encourage children to avoid brushing their teeth immediately after consuming acidic food or drinks as this is when the enamel is at its softest - it's best to wait as long as possible after an acidic meal or brush beforehand,” Steele added.
