How would you fix this collapsed v inverted nose deformity, wide nostrils, and my smile line with bottom teeth showing? (photo)

You need a careful consultation to evaluate the nose.  Sometimes filler can be used to straighten out a collapsed area but it does not make the nose thinner.  The upper lip retraction (gummy smile) can often be nicely improved with botox injections (off label).  Make sure to see a board certified specialist.Best of luck.

For the small depression on the right side, a cartilage graft may be beneficial to camouflage it. Botox will not lift the lip.  A lip lift procedure is probably not necessary but an exam in person would be helpful.
