Sometimes: Sometimes it's hard to tell. If it's in the back, lower jaw, and alternates between sides, more likely wisdom teeth. Try OTC pain meds until you can see your dentist. For best results with wisdom teeth, make sure you are evaluated and treated by a board certified oral & maxillofacial surgeon.

What difference: You are in pain. Pain from infected tooth or from problematic wisdom tooth is still pain, and may feel the same. You must see a qualified professional to diagnose and treat your problem. This isn't a DIY project. Call a Dentist now, before the problem worsens.
