"How did Britain stack up?
The UK came in third place when it comes to knowing the risks associated with poor dental hygiene and lifestyle habits – behind Canada and New Zealand. But we came in sixth place when taking steps to prevent those – putting us behind Brazil and Mexico at the top of the chart.
How did the US stack up?
While we might have a bit of ‘brushing up’ to do, not as much as our US cousins it seems.
America came in ninth when understanding the right steps to take to keep their teeth pearly white. And a shocking tenth for acting on that advice.
That’s not all, in 2015, Harvard University conducted research into the number of missing teeth in the average mouth. It found that Americans are missing 7.31 teeth on average, compared to Brits who are missing 6.97.
That’s not all. Those with the worst teeth in Britain tend to be our older citizens, but in the US those with no teeth at all are actually of working age."
