Should I straighten teeth before root canal and crown placement, or after? (Photos)

I would suggest doing root canal first..Also check vitality of your other front tooth as canal looks more narrow as it appeared also injured awhile ago...Moving a dead tooth before a root canal could make a dormant infection flare up during straightening ..After root canal and invisalign veneer front tooth bothering you...I would suggest however veneering both centrals as final result will please you more

Hi:If you need a root canal, do the root canal first, then straightening with Invisalign prior to whitening and crown.Best,Dr. Maddahi

I think you should first go for root canal treatment then Invisalign and after that Teeth Whitening treatment would be better.
