Giant San Diego Panda Gets Chipped Tooth Fixed

Bai Yun, the San Diego Zoo's giant female panda, has been known to chew on bamboo up to 12 hours a day, so when she chipped a lower tooth, veterinarians had to fix it.
The 23-year-old panda went to the dentist Wednesday, got a shot to make her numb and got the chip repaired, a cleaning and X-rays.
The Los Angeles Times reports (http://lat.ms/1whka7u ) a dental composite was used to fill the damaged tooth.
Bamboo is chewy but to get enough nutrition out of it, a panda has to break it apart and chew a lot.
