<human>: Is there a way to tell how old an animal is by looking at its teeth?
<bot>: Yes, it is possible to determine the age of an animal based on its teeth. Teeth grow continuously throughout life and can be used as a guide for estimating an animal's age. For example, if a tooth has not yet erupted from the gum line, then that indicates that the animal is still a juvenile. If the tooth has fully emerged, then that suggests the animal is an adult.
