Can Invisalign Work with Receding Gum Issues That Are Semi-under Control?

Even if the teeth are straight, the soft tissue and bone supporting the teeth may not look as desired. A consultation with a periodontist would be best.

If there is active inflamation in your gums you should get it under control before starting any tooth movement, whether with braces or Invisalign.  Your dentist or a periodontist should be able to tell you with a high degree of accuracy if your gums are healthy enough for tooth movement.  The crown may need replacing in order to obtain the most esthetic result, and if this is planned make sure the dentist, periodontist, and orthodontist coordinate their care.  You didn't mention this but sometimes protruding front teeth can be exacerbated by a bite problem.  If this is the case you may wish to discuss having the bite corrected as well as the teeth straightened. 

Good direction from other doctors.  Yours is a definite coordination case and periodontal health is important  as is a replacement of your crown and evening out of gum tissues for best end results.  This would end up giving you a gorgeous end result.  Definitely involve your dentist and a periodontist (gum specialist) which he can refer you to to verify gum health.  Your dentist can do the Invisalign, if he is certified, or send you to an orthodontist. The porcelain replacement for the crown can also be done by your dentist but he may want to involve the periodontist with aligning the gum tissues after Invisalign is completed and before the crown is replaced.  Good luck!
