That's a good question! What has your dentist told you? Have you had a recent panoramic x-ray? Are they completely erupted?
Most dentists like to wait till kids are about 16-18 to get the 3rd molars out. In fact, most kids don't even get them until they are over 16.
Best thing to do at the present time is to make sure you keep them as clean as you possibly can.
