How long does it take to treat a finger dislocation?

Depends: Treating a dislocation can be immediate if the joint returns back to its normal position. If it does not go back in place, a doctor can manipulate it to get it into proper position. Sometimes, the joint will be really stuck and you will need surgery. Healing a dislocation can take time. Residual swelling is common. Doing proper finger exercises will help prevent permanent stiffness.

Hard to say: Treatment may be relatively simple but recovery may be prolonged for several months or years and may even require surgery if associated with a fracture or joint injury. If unstable surgery may also eventually be recovered. Swelling may persist for years after even a simple dislocation.
