Would I benefit from veneers? How many should I consider? (photos)

Obviously, a thorough clinical evaluation during a consultation would be needed, however, based off of the photos that you were showing, I would urge you to consider to first Align, the teeth with clear aligners, so that heights and root angulations are in proper form prior to veneers. I would keep equalized spacing between some of the teeth to minimize the amount of preparation needed for the veneers. So in short, based off of these photos, I would suggest short term, clear liner treatment, followed by 8 to 10 upper veneers and 8 to 10 lower veneers.
