I Needed a Root Canal but Ignored the Fact. I Am on my 2nd Week of Invisalign and my Tooth Hurts. Should I Wait a Whole Year?

You NEED to address the root canal, pain will only increase. Get the root canal ASAP. This treatment trumps invisalign.

You should absolutely take care of the infection with a root canal if that is what was recommended. The gum or bone or root of the tooth might have permanent damage if left for a long time such as you suggested. Be sure the person doing the filling over the root canal knows you are wearing the trays and show it to the dentist at the beginning of your appointment. Besides, why have a sore tooth for a year? Good luck - hope this helps.

Dental work including root canals need to be addressed before orthodontics including Invisalign, but since you have already started with Invisalign, you should address the root canal situation right away.  Your Invisalign doctor should be aware of this and work with you to resolve the issue.  If you were my patient, I would keep you in your first aligner until the root canal is completed.  You may have some positive news in that when the RCT is completed the tooth anatomy may not be altered.  Major work such as crowns need to be avoided during Invisalign treatment as the aligners may not fit after a crown is made.  Once your RCT is completed, you should be able to continue with the remaining aligners and finish the treatment as originally designed.
