Millions snacking on sweets after dinner and skipping the toothbrush, research reveals
Published: 27/05/2025
Millions of people across the UK are putting their oral health at risk by snacking on sugary treats after dinner and failing to brush their teeth before bed, research from the Oral Health Foundation has revealed.
Findings from the charity show one-in-three (33 per cent) adults are snacking every night after their evening meal, with more than two-in-three (68 per cent) snackers opting for sugary treats like chocolate, sweets and biscuits.
At the same time, nearly half (47 per cent) go to sleep without brushing their teeth at least once a week, allowing sugar and bacteria to damage their teeth overnight.
The charity has warned that this dangerous double habit could lead to a rise in tooth decay and gum disease.
Nigel Carter, chief executive of the Oral Health Foundation, said, “These figures are a real wake-up call – the UK is becoming a nation of late-night snackers, and it’s our teeth that are paying the price.
“Snacking on sugary treats every night and then skipping brushing before bed is a recipe for disaster. When you don’t brush, sugar and bacteria stay on your teeth all night, producing acids that eat away at the enamel. Over time, this can lead to tooth decay, gum disease and tooth loss. Essentially, you’re giving harmful bacteria free rein to damage your mouth while you sleep.”
The charity’s findings revealed that up to 26m British adults are tucking into sugary treats after dinner at least three times a week.
The research revealed that young adults are often the worst offenders with more than four-in-five (86 per cent) 18-to-24-year-olds admitting to snacking at night, with most (81 per cent) reaching for sugar-packed treats.
Young people are also the most likely to skip brushing their teeth before bed. Nearly half (43 per cent) said they miss the nighttime brush a few times a week – well above the national average of around one-in-three (36 per cent).
Nigel has said the message is clear – avoid snacking after your evening meal whenever possible.
He added, “If you do choose to snack, pick options that won’t harm your teeth. Savoury choices like cheese, nuts, or breadsticks are much better for your oral health.
“Save sugary treats for mealtimes and always remember – brushing your teeth before bed is essential. It’s your last line of defence against tooth decay.”
