Angela Debley took her son Fin, then eight, to the dentist for a check-up, confident that he’d be given the all-clear.
After all, Angela, an admin manager from Bracknell, Berkshire, was a self-confessed ‘health freak’ who was always careful to give her two sons, Fin and Joe, then three, a nutritious diet. She was also meticulous about their dental hygiene.
‘I avoided giving them sweets in favour of what I believed was an extremely good diet full of natural foods,’ says Angela, 40.
‘Instead of fizzy drinks, chocolate and crisps, the kids would have pure fruit juice, muesli bars and granola with natural yoghurt and honey. They also brushed their teeth morning and night.’
When the dentist broke the news that Fin had two cavities in his milk teeth, which had developed since his last appointment six months before, Angela says she ‘felt like the worst parent in the world’ – but she couldn’t work out where she’d gone wrong.
‘The dentist seemed to assume I was feeding him junk food and sweets, which was upsetting because we ate well.’
In fact, it was her children’s healthy diet – and particularly their snacking habits – that had caused the damage.
Angela later learned it wasn’t just the quantity of sugar that was the problem, but the frequency with which teeth are exposed to it. ‘By offering juice, fruit and honey between meals, I was bathing my sons’ teeth in sugar and acid.’
As Professor Damien Walmsley, scientific adviser to the British Dental Association, explains: ‘Children today snack far more often than previous generations, which leaves teeth under constant attack.’
Last month, a Royal College of Surgeons report revealed that one-third of five-year-olds in England suffer from tooth decay, and it is now the leading cause of hospital admissions for under-nines.
The report, The State Of Children’s Oral Health, found that every year 46,000 children were admitted to hospital for multiple tooth extractions – almost 26,000 of those aged between five and nine.
Professor Nigel Hunt, of the Royal College of Surgeons, blamed sugary foods and drinks, saying these should carry cigarette-style warning pictures to highlight the risk to children’s teeth.
But the problem is certainly not confined to children brought up on junk food, or who aren’t taken to the dentist regularly. In fact, dentists say they are seeing more and more children from middle-class homes whose health-obsessed parents are inadvertently harming their teeth.
There are two ways in which these kinds of foods damage teeth. One is acid erosion, which occurs when teeth are exposed to acidic foods such as fruit and juice. Dried fruit such as raisins may cause acid erosion, too.
Tooth enamel begins to soften and be destroyed when acid levels in the mouth drop below 5.5 on the pH scale. (Water has a pH of 7, oranges have between 3 and 4.)
After 30 minutes to an hour, saliva, which is alkaline, will restore natural pH balance in the mouth and the enamel will harden, but if the exposure to acid is too frequent – as caused by constant snacking – then the enamel begins to wear away.
This not only makes teeth more vulnerable to decay, but if teeth are brushed within 30 minutes of acid exposure, the softened enamel can be literally scrubbed off.
‘As children’s milk teeth have thinner and softer enamel, they are particularly at risk,’ says Dr Hanel Nathwani, of Reading Smiles in Berkshire. The second major threat is sugar. As Professor Walmsley explains: ‘Bacteria that live in the mouth cause decay, because as they feed off sugars they excrete an acid that attacks enamel in a similar way to acid erosion.’
These bacteria love refined sugar most, but they also feed on honey, and even processed starchy foods such as bread.
‘Acid attacks can last for up to an hour, but teeth can recover provided you limit the sugary foods and drinks to mealtimes only,’ says Professor Walmsley.
Even if it’s only the milk teeth that are affected, this can still lead to long-term problems.
He adds: ‘I often see parents who feed their families generally great diets and are very shocked when they learn that their children have tooth decay because of these apparently healthy foods.
‘I feel for them, as they are trying their best to do the right thing.’
This rang true for Angela. Fin and Joe would have four or more snacks a day, such as granola and honey mid-morning, milk at night, plus juice and fruit whenever they wanted it during the day.
She used to give her sons muesli bars as an after-school snack.
‘I thought they were a healthy alternative to sweets and biscuits, but after I moved the family to Dr Nathwani’s practice, I looked more closely at the labels and noticed they were packed with more sugar than a chocolate bar.’
Angela gave the children milk before bed, thinking the calcium would be good for their teeth. However, Dr Nathwani says: ‘While milk during the day is fine, the lactose in it is a type of sugar and can be harmful at night, as when we are asleep we produce less of the saliva that would neutralise it
Angela is far from the only health-conscious parent to discover she’s unwittingly exposed her child to tooth decay.
Louise Jones (a pseudonym, as she’s too embarrassed to give her real name) discovered her ‘fruit monster’ son needed four fillings at the age of seven because he constantly snacked on oranges, grapes and apples.
‘My family call me the “fridge Nazi” at home, because I’m so careful with my children’s diet,’ she says. ‘I was very proud that he loved fruit so much.
‘I was horrified when his dentist told me that my son had such bad teeth because constant exposure to acid in fruit was literally dissolving the enamel on his teeth. I now give fruit at mealtimes and just once a day as a snack.’
The fad for smoothies doesn’t help, as Dr Uchenna Okoye, of London Smiling dental practice warns. ‘Juice from fruits has a high acid content and can damage the enamel of your teeth in exactly the same way as fizzy drinks do.’
Six rules to save their smiles
- If you allow your children fizzy drinks, give them a straw to minimise contact with teeth.
- Reduce snacking. Snacks should be savoury, such as a cheese sandwich, to neutralise acidity and stimulate saliva.
- Children should brush their teeth at least twice a day using a fluoride toothpaste. This repairs and hardens enamel and reduces the acid that bacteria produce.
- Avoid brushing immediately after eating, when enamel may be softened. So brush first thing in the morning or, ideally, 30 to 60 minutes after breakfast.
- Serve juice only once a day with a meal.
- Avoid giving milk after they’ve brushed their teeth at night.

Angela has now made simple changes to her children’s diet to protect their teeth from further damage. ‘We hardly snack now and eat more filling meals instead.’
If the boys do need something extra, she offers them a cheese or ham sandwich.
‘Sweets are eaten only on Friday, when we have family movie night. This has made them more of a treat, and they know to brush their teeth an hour after eating them.’
Six years on, neither of her sons has had a filling.
Some children may be more vulnerable to tooth decay anyway. As Professor Walmsley explains: ‘Some children are born with hypoplasia, where the enamel hasn’t formed properly.
‘Bacteria can hide in the defects, prolonging the acid attack, which means teeth are more prone to decay.’
Hypoplasia is linked to fevers in pregnancy when the child’s enamel was being formed, and courses of antibiotics.
