North Berwick veterinary dental specialist Norman Johnston got to the root of the problem when he was asked to help a polar bear with toothache.
He and his veterinary nurse Claire Harrison, who lives in Haddington, joined a team of 12 experts to help the four-year-old animal called Arktos - a star attraction at the Highland Wildlife Park, Kingussie.
Keepers had noticed that the usually playful 75 stone polar bear seemed to be feeling a bit sorry for himself and was not hanging out with his polar pal Walker quite so much.
Then regular checks revealed that poor Arktos might have toothache and a small area of discolouration was found on his upper left canine tooth.
The Royal Zoological Society of Scotland’s team of veterinarians and dental experts, including another Haddington veterinary nurse Donna Brown, were called in.
