Some professionals are reluctant to indicate orthodontic traction, especially for upper canines. Among the most common reasons for restricting the indication of orthodontic traction are: 1) Root resorption in lateral incisors and premolars. 2) External cervical resorption of the canines under traction. 3) Alveolodental ankylosis of the canine(s) involved in the process. 4) Calcific metamorphosis of the pulp and aseptic pulp necrosis.
