Are my teeth too big for crown lengthening? (photo)

Before committing to gum surgery I'd suggest you explore the option of using Botox to cosmetically drop your lip line.  Many dentists are well trained in this area and it's a much less invasive treatment for a gummy smile. Good luck!!

Yes, crown lengthening will make your teeth appear longer than they are currently. If you have a high smile line, or a very mobile upper lip that raises higher, showing your gums - crown lengthening will not resolve that problem. In order to fix that, you may have to consider a surgery to have your upper jaw (maxilla) adjusted to hide some of the gums. If you are a candidate, you could also consider botox injections to minimize the movement of your upper lip so that you dont show as much of your gums when you smile. Botox is only a temporary fix, and you would need to do injections frequently (3-4 months) to maintain the effectiveness of it.
