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. The hilarious photographs were captured by British photographer David Williams, 41, on a visit to Tama Zoo, in Hino, Japan. David, from Bangor, Wales, says: “In these pictures you can see a macaque looking inside a friend's mouth, searching for fleas or insects.
