It depends on whether they are causing immediate problems. If you are experiencing tooth pain, swelling, difficulty chewing, have an infection or abscess, or other complications, immediate removal is necessary to properly treat the problem.
If you do not have symptoms, x-rays and examination by a dentist or oral surgeon are the only ways to determine whether wisdom teeth removal is a dental emergency. Extraction may be needed if there is damage below the gum line or the tooth roots are causing harm.
