Is Lip Lift the Only Way To Show More Teeth? (Photo)

I've been thinking about a lip lift because I don't show much of my upper teeth when I talk or smile. But I'm concerned that in the end it won't actually help because maybe it's a larger facial structure issue. I've noticed some aging celebrities whose upper lips have lengthened noticeably, but their teeth are still visible. Plus, I don't want to change the size or shape of my lip. So I'm wondering if I should nix this idea or look for another way. Thanks.
