Only half of my teeth show when I smile. How can I fix it?

my TEETH are long but my gums are not. the length between my upper lip and nose is short too [ not the problem ]. i have even been keeping my teeth; upper and lower, a little apart [ ≈ 0.5cm ] all these years to fix the no-teeth look when i close my mouth. my teeth are weird anyways so i was thinking of pulling them all out and getting implants [ not dentures ]. i haven't looked into it yet but i was wondering if i could fix the short-gums problem in the process with bone grafts or whatever.
