I Have Just Finished my Root Canal Treatment, How Long Should I Wait to Get Orthodontic Treatment?

Performing orthodontic treatment following root canal treatment on a tooth depends on the condition of the tooth before, during and after the root canal treatment has been performed. For example if a severe dental abscess was present prior to the root canal treatment, any complications (flare ups) during treatment, and the restorative needs of the tooth after treatment can all indicate the need to wait a period of time, or not, prior to beginning orthodontic therapy. Any infection should be resolved, and any restorative treatment such as a post or crown should be performed prior. On the other hand, orthodontic treatment could be performed almost immediately following a straightforward root canal treatment on a tooth devoid of an abscess or additional restorative needs. 

While 6 months would be ideal, I feel that as long as the orthodontist is made aware of the root canal, and he can follow it on an X-ray, he can begin the ortho after a month and continually monitor the situation.
