Zookeepers previously used ordinary brooms to brush the hippos' teeth. But last summer, they updated the tools with 1.5 meter (5 foot)-long toothbrushes.
Like all animals, hippos can get cavities and gum disease when food sticks to their teeth. That's why even wild hippos by to keep their teeth and gums clean and healthy. They use their tusklike canine teeth to strip bark from trees, which acts as "hippo dental floss."
The zoo's hippos seem to enjoy the new brushing routine, says Tracey Lee, one of the zookeepers: "They really chill out when they're having it done."
