<human>: Is there a way to tell how old an animal is by looking at its teeth?
<bot>: Yes, there are several ways you can tell how old an animal is by looking at its teeth. One of the most common methods is to look for signs of wear and tear on the teeth. As animals age, their teeth will become worn down due to chewing. You can also look for changes in tooth size or shape that may indicate aging. Additionally, if you have access to x-rays of the animal's mouth, you can compare them with previous x-rays to see any changes.
