Quote:Wild gorillas eat mostly plants and have fewer dental problems than more omnivorous species like chimpanzees, which consume fruits, nuts and animal protein much as cavity-riddled humans do. Scientists have found that animals undergo distinct morphological changes in captivity; some species grow larger skulls, for example, while others get more cavities. Captive gorillas live as much as 20 years longer than their wild counterparts too, reinforcing the need for a basic dental-hygiene regimen. At Zoo Atlanta, willing gorillas have their teeth brushed several times a week, and dentists are on call to drill out decay and perform the occasional root canal.
