Scientists have found having straight teeth has a beneficial side-effect: it improves our sense of balance and posture. People with ‘overbites’ or ‘underbites’, crowded teeth or wonky teeth are more wobbly on their feet, according to a new study. Having a bad bite meant worse balance particularly when the subjects were tired, the researchers found.
It may also have an affect on athletes, playing a key role in how well they perform, as well as making them more likely to get sprains, strains and fractures when they become more tired.
The studies were carried out by the Department of Physiology at the University of Barcelona and the University of Innsbruck.
