How do I know if I need a wisdom tooth extraction?

I'm 24, and my gums and teeth have been causing me a lot of pain, probably my wisdom teeth. How would I know if I need a wisdom tooth extraction?

Make an appointment to see an Oral & Maxillofacial surgeon. He/she will take an X-ray and be able to consult you about the sty.

You need to see your dentist or an oral surgeon for an examination.
