<human>: Is there a way to tell how old an animal is by looking at its teeth?
<bot>: No, there is no way to tell how old an animal is by looking at its teeth. Teeth are made of enamel and dentin which can be worn down over time. Enamel is the hardest substance in the body, so it doesn't wear away as quickly as other tissues. So you can not tell how old an animal is by looking at its teeth.
