Short upper lip, lip incompetence but no gummy smile, what are my options?

you may get similar relief as a patient who receives Botox injections to lower their upper lip not to show their gum line when they smile. If you have had lip filler and this issue with incisors showing only occurred after lips were filled then hold off on Botox injections to allow the filler to dissolve and see how the shape of the mouth returns.The information provided in Dr. Shelton's answer is for educational purposes only and is not intended to constitute medical advice.  The information provided should not be relied upon as a substitute for consultations with a qualified health professional who may be familiar with your individual medical needs. 

Since your upper lip does not apparently function in a normal way, I believe you would be best served to consult with a maxillofacial surgeon who has some cosmetic training, such as Joe Niamtu, DMD in Midlothian, VA (just west of Richmond).  Joe is extremely personable, and passionate about these matters, and is well networked....so he could likely recommend someone close to where you reside.
