What Cosmetic Dental Procedure Would I Have to Undergo to Gain a Perfect Smile? (photo)

You have a few issues. Narrow arch, midline off centered, lots of spacing, and ill proportioned teeth size. You first need orthodnotics, then full arch veneer/ crown restorations. Based on the after ortho result , you can get a better idea of your future smile with veneers. At this time, you are simply guessing your smile design. And always remember, cosmetic dentist can do so much with what they are given to start with . Good Luck.

Based on the photos, it looks like there is too much spacing to create appropriately sized teeth. Othodontics would level and align the arches and consolidate the spaces. Invisalign may work as well. Prior to finishing the orthodontics impressions and a diagnostic wax-up should be done to see if the spacing and teeth possitions are correct. This will show you how the teeth will look on a model of your mouth. Finally veneers will give you the ideal tooth shape, size, and... more

I think that the most ideal treatment for your situation would require a combination of orthodontics (braces) and porcelain veneers. Orthodontics would correct your narrow upper arch and midline discrepancy. Braces would set the teeth in a great position so that you could have a fantastic smile makeover where the teeth would look natural and proportionate. Find a great orthodontist and cosmetic dentist and you will be well on your way. Good luck.
