Hi:Normally when teeth are too wide I do not recommend lumineers since very little to no tooth structure is removed when doing lumineer therefore the teeth will appear bigger and wider after placement of a lumineer.In my opinion all of the four teeth appear to be too far out as a result the teeth have to be shaved down more than the thickness of the final veneers to make them appear more narrower, shorter and more inline with your other teeth. This will require regular veneers.The other option is to do orthodontic treatment and strip between your teeth to push them back and at the end do minor contouring to make the two front teeth shorter. In this option you basically keep your own natural teeth.Best of luck!
Thanks for posting the picture. You didn't exactly say where you want the Lumineers placed. If you are thinking about putting them on your side teeth to create a broader smile that matches your front teeth then you might be a candidate. If you are trying to make your front teeth look less prominent Lumineers are not the answer. I would suggest having a consultation with an orthodontist to bring these teeth into a more ideal position. I hope this answers your question.
