Can my bottom crooked tooth be straightened with porcelain veneers? (Photos)

You would be a candidate for porcelain veneers if you did not want to revisit orthodontics.  8-10 veneers would give you the most optimal result.  Good luck.  

u have both options open . as u have good teeth so , u can continue with invisalign. invisalign FULL is ideal option for u because u have bolton's discrepancy. i feel , yr doctor choose another option and thats why its not fully corrected.but now if u want to shift to veneer , u can proceed with that also. lower 8 or more porcelain veneers are recommended.   

Thanks for your question and I completely understand how you feel about doing Invisalign again! In reality, Invisalign doesn't always finish the way its projected on the computer.
Veneers are an excellent option for teeth that are slightly crooked and not perfectly straight. These thin shells of porcelain are permanently bonded on the front of your teeth to correct many cosmetic issues, including crowding. 
Because your teeth are overlapped and stacked in front of each other, I would recommend a minimum of 4 veneers. Even with veneers, your teeth can move back so make sure you wear a retainer nightly!
