My Left Lip Does Not Go Up when I Smile. You Cannont See my Teeth. What Do I Do?!

This is indeed an interesting problem, and demands study by a skilled and experienced plastic surgeon, and a circumspect approach.  Your seventh (facial) nerve function should be carefully examined.  If intact, I would consider a unilateral (left sided only) lip lift... although this is certainly NOT a perfect solution.  The lip lift is a static procedure, and will lift the left side in repose, but may not change your smile sufficiently for you.  An internal (mucosal) resection may help also.  There are other possibilities, but those procedures are more complex, and normally reserved for patients with seventh nerve dysfunction. 

Thank you for the photos and I can appreciate your concerns.  To answer you question regarding fuller lips, yes the lips can definitely be augmented with a procedures to allow more fullness.  This can be done with fillers, fat grafting, as well as implants.  My main concern is the weakness which you display at the left upper lip.  There seems to be weakness of the facial nerve in this area which is causing the lack of lip elevation on the left.  I would suggest to first undergo a comprehensive head and neck evaluation to possibly find out the etiology of this weakness.  Good Luck...

The fact that your left upper lip will not move up when you smile means that, for some reason, the facial nerve does not work properly.  This can occur through a variety of different mechanisms including trauma, previous surgery, previous treatment of other disease (eg, for cancer), or it can just be something that you were born with.  There are a variety of techniques that can be used to improve the symmetry of your smile.  You should discuss this with a physician with expertise in the treatment of facial nerve disorders.  Usually this is an otolaryngologist, or a facial plastic surgeon.
