How can I improve the amount my teeth show when I smile? (Photos)

Hi, when I smile my teeth barely show which makes me self conscious. When I hold my nose up, you can see my teeth like I wish they showed normally. Ive had a consultation for a lip lift but the MD said it wouldn't help due to your smile being controlled by facial muscles. Would dental bonding help the amount my teeth show? My teeth are not bad so I wouldn't want to get veneers and shave them down.
