A young Japanese macaque is captured by the camera while cleaning the teeth of an older member of its pack in a wildlife zoo of Bogor, Indonesia. It took about 30 minutes for this macaque "dentist" to look for any lingering scraps of food in the elder's teeth.

The Japanese macaque is also known as the snow monkey, usually famous for enjoying hot springs in the winter.

Japanese macaques take great care of their dental hygiene, so they usually clean their teeth after every meal. They even pass on the "dental cleaning techniques" to their offspring.
