Teeth in the animal world

Caring for teeth is important both for humans and pets. We need to brush our teeth twice a day, and brushing is the best way to keep Fido’s teeth clean as well. There are also chews, dental spray, and dental wipes that might assist with the cleaning process.

Human children have 20 baby teeth that fall out. Human adults have 32 teeth. Puppies have 28 teeth and adult dogs have 42.

42 teeth sounds like a lot, but it’s nothing compared to some other animals. A white shark has about 24 exposed teeth on their top and lower jaws respectively, but behind these 48, a white shark can have five more rows of developing teeth. When the shark loses one of the main teeth, a developing tooth rotates in and replaces it.

Alligators have a similar system. An alligator has an average of 80 teeth in the mouth at any one time, and when one falls out another takes its place.

Dolphins also have a surprising amount of teeth. An Atlantic bottlenose dolphin has between 80 and 100 teeth. The short-beaked common dolphin has around 240.
