A new survey found that people have cleaned their pearly whites in obscure spots such as the Great Wall of China, on safari in the Masi Mara and in a bomb shelter in Israel.
Camping in Yosemite National Park and the Australian Outback were other answers, while closer to home some men said it was in the delivery room while their partner gave birth.
The survey was carried out by the British Dental Health Foundation as part of National Smile Month.
Chief executive Dr Nigel Carter said: “So many of us seem to take our toothbrush wherever we go – mountains, jungles and even dates. This is good news as it shows just how many people understand the importance of regularly brushing their teeth.”
It’s definitely got me thinking . . . what about you, where have you brushed yours??
