Professional footballers have worryingly poor teeth that could be affecting their

performance on the football ground, say dentists. Their study on players at eight clubs in

England and Wales, in the British Journal o f Sports Medicine, showed nearly 4 0ut of 10

had cavities （蛀牙) and that athletes often had worse teeth than the general population.

Regularly taking sugary foods is one possible explanation.

   The dentists, from the International Centre for Evidence-Based Oral Health at

University College London, examined 187 players' sets of teeth. They found 53% had

dental erosion (腐蚀), 45% were bothered by the state of their teeth and 7% said it

affected their ability to train or play. Around 40% had cavities, compared with 30% of

people of a similar age in the general population.

     Prof Ian Needleman, one of the researchers,  said:  "These are individuals who

otherwise invest so much in themselves so it’s a surprising finding.

    "There are two main groups - some have a catastrophic effect, they have very

serious disease that stops them in their tracks and they cannot play or train.

       "There Il be others experiencing pain affecting sleep or sensitivity every time they take

a drink. "

      At this level of athlete, even small differences can be quite telling.

      Nutrition is one of the primary suspects with having too many sugary or acidic foods

during training potentially accounting for cavities and erosion. A lot of air in the mouth

during exercise can also dry it out so there is less protection.

    While these findings are worrying, clubs are attaching greater importance to dental

health and educating their players. According to Stijin Vandenbroucke, head of medicine

and sports science at West Ham United, oral health is an area where many athletes have

greater problems than the general population and there are clear benefits of oral disease

prevention for athletes and clubs.
