What to do to fix gummy smile? I have small teeth and a gummy smile. (Photo)

A dentist told me once to get veneers but there are way too expensive. Also ive been told to get jaw surgery but the idea of surgery scares me. Ive heard that TADs can help reduce a gummy smile by bringing up the teeth, im interested, is it effective? Is the result permanent? Also my lateral incisors dont match the rest of my smile, they even smaller, what do you recomend for these? I would really like to avoid putting veneers on all my teeth at all costs.
