<human>: Is there a way to tell how old an animal is by looking at its teeth?
<bot>: Yes, there are several ways to tell how old an animal is by looking at its teeth. One method is to look at the wear and tear on the teeth. Teeth that are worn down can indicate that the animal has been around for quite some time. Additionally, the number of tooth roots can be used as a gauge of age; animals with more roots will generally have lived longer than those with fewer.
