How old is it considered early for your wisdom teeth to erupt?

Varies: It really depends. Some kids start getting theirs in at 14-15, some aren't coming in until their mid to late 20's. A lot depends on the direction the teeth are pointing and whether or not they a going to have room to come in. In a nutshell, wisdom teeth can be relatively unpredictable. See your dentist, consider having a panoramic radiograph taken, and get your dentist's advice.

Depends: Wisdom teeth can come in any time in a wide age range, and keeping in mind that everyone develops at a different rate, this probably isn't a major worry. A panoramic x-ray at the dentist can help identify any problems that this might cause. I've seen them come in anywhere from 14-30 years of age.
