This cheeky macaque gets up close and personal as he examines the dental hygiene of his fellow primate. Using his fingers to prise open his friend's mouth, he carefully inspects his teeth, searching for any unwanted visitors.

David, from Bangor, Wales, says: “In these pictures you can see a macaque looking inside a friend's mouth, searching for fleas or insects.
