A study has shown that gamers are twice as likely to suffer from manky teeth as their non-gaming contemporaries.
Because teenagers tend to sit in front of their consoles for hours on end, they don't eat properly, tending to graze of sugary snacks and acidic fizzy drinks rather than sitting down to proper meals.
Dr Nigel Carter, chief executive of the British Dental Health Foundation, said, “Every time you eat or drink anything sugary, your teeth are under acid attack for up to one hour.
“This is because the sugar will react with the bacteria in plaque – the sticky coating on your teeth – and produce the harmful acids.
“So it is important to keep sugary foods only to mealtimes, limiting the amount of time your mouth is at risk.
The problem is that the same report estimates that 97 per cent of all teens in the UK regularly play video games.
It's only a matter of time before the health warnings on games boxes are telling us to take regular breaks, and brush our teeth between levels.
