<human>: Is there a way to determine a person's age by using their teeth?
<bot>: Yes, there are several ways to determine a person's age by using their teeth. One method is to count the number of tooth surfaces that have erupted in the mouth. This can be done by looking at the number of permanent teeth and deciduous teeth present. Another way is to measure the length of time since the last dental eruption. The amount of tooth wear can also indicate an individual's age.
