When is a fiberotomy necessary?

After Othodontics. A fiberotomy involves the detachment of the fibers that attach the tooth to the bone via the gum. The fibers act much like twisted rubber bands and releasing the tension between the fibers and the tooth reduces the forces that attempt to pull the tooth back to its original position. It is performed near the completion of the orthodontic treatment and is shown to be effective in preventing relapse.
