Elite athletes have bad teeth despite putting more effort into looking after them than other people, a study shows.
UCL scientists interviewed 352 British athletes, including those preparing to compete at the 2016 Olympic Games in Rio, Brazil.
It showed they were far more likely to brush twice a day and floss between their teeth, but still struggled.
Researchers said athletes need to take more steps to look after their teeth, such as high fluoride toothpastes.
Around half of elite athletes in the UK have signs of tooth decay compared with around a third of similarly aged adults.
The latest study, published in the British Dental Journal, attempted to explore why.
