Maxillary length 15 teeth, mandibular length 13 teeth. What's going on here?

Now most people have 28 teeth and 4 wisdom teeth. Some people are long, some people are not long, some people are not necessarily long, maybe one or three.

According to the specific situation, wisdom teeth can be kept or pulled out.

However, you two friends had to pull out their teeth because they didn't face the mandibular teeth for a long time, and a single tooth would grow slowly and cause damage to soft tissue because it didn't face the teeth, so it needed to be pulled out.

Advise them to see a doctor as soon as possible.

Your friend 13 has an embedded tooth or a birth defect. Better have a check.

If you think the fortune teller is right, you can keep it for verification.
