I have had a smile that has gotten progressively more crooked over time (Photo)

It is possible that your smile issue is related to your migraines. I would find an LVI trained neuromuscular dentist to check you out. You can get more information at migrainedentistry.com about neuromuscular dental treatment.  Also, if that all checks out, a good cosmetic surgeon should be able to use facial fillers and botox to straighten the smile.Good luck and feel better

Hi from Massachusetts!  I think that your smile is related to your Migraine headaches you are having. Maybe there is too much pressure on the facial nerve that controls that part of your smile and your left upper lip.  It there is enough pressure for periods of time, I would think it could damage the nerve that controls that side of your smile.  I am not a neuromuscular  dentist but find one close to where you live and let him check this out. Boston has many dentists who are trained in this area.  I think your smile is getting worse because of pressure on that particular facial nerve.  Call and set up a consultation with one of these doctors before you do any facial fillers or Botox injections!
