Damaged Captive Orca Teeth (image) University of Otago Share Print E-Mail Caption An international research team has undertaken the first in-depth investigation of the teeth of captive orca (killer whales) and have found them a sorry state, which raises serious concerns for these majestic mammals' overall health and welfare. Anyone with a toothache knows how painful and distracting that can be - in orca which have around 48 large teeth, a sore tooth is likely no less painful or debilitating than for a person. Now, a new international study published in the journal Archives of Oral Biology, found that every individual examined had damaged teeth. Credit Ingrid N.
