Bai Yun recently had to visit the dentist to have a chipped tooth fixed. Giant pandas use their teeth to chew and break apart bamboo, so their teeth can get worn or damaged over time. Giant pandas such as Bai Yun, a mother of six, can spend up to 12 hours a day eating bamboo, which is the primary source of their nutrition. The procedure went well and she’s back to munching bamboo like a champ, much like her friends on the live cams.
