I just got my wisdom teeth removed a week ago. one side has healed and the other is still in extreme pain. how can i heal it or fix the pain?

Follow up : I suggest you follow up with the oral surgeon who removed your wisdom teeth. You may have a "dry socket" or infection that requires immediate treatment.

Needs examination: You should give the dentist who extracted your teeth a call for a follow up exam. You may have a dry socket or an infection, or a pice of bone, or it may be nothing and it's just taking longer to heal. Hard to say exactly what the cause is without visualization. All the best...
