My teeth don't support my smile; thin lips only when smiling; short, narrow smile; what are my options? (Photo)

Hi there,
You appear to have a low smile line with no gum display in a full smile. Your lips thinner in a full smile and the you display about 3-4 mm of your upper teeth in a smile. I am guessing that in a profile view, your upper teeth tip inwards which may be why your lips tuck in and get thinner in a full smile as they are nice and full at rest. The buccal corridor negative spaces on both sides of your smile are large which hints that you have a narrow or tapered upper arch. The short lower face height from a frontal view hints that you have a smaller lower jaw than upper, hence the horizontal overbite or overjet.
My thoughts are towards Invisalign or orthodontics to align the upper and lower teeth and widen the arches. The upper teeth may be tipped forward a bit to help support your upper lip, but I am guessing here as I do not have a profile photo or other records. 
Cosmetic dentistry and veneers will enhance the final outcome, but I would not select that as my first choice.
Hope this helps you with your decision!
Best regards,
Dr. Ed Lowe

Hi:It is difficult to fully diagnose the problem with the photos you have provided, however you should consult an orthodontist and an experienced cosmetic dentist to explore options of supporting the upper lips better with your upper teeth.Best,Dr. Maddahi
