Please tell me if you can put dental veneers over an implant?

Implant crown ?: If i understand the question, you can build a veneer over a porcelain implant crown. It requires preparation of the porcelain crown to create space, just like it would for a tooth. Might be as cost effective to have crown rebuilt or remade, depending upon if it is screw-retained or cemented. Good luck.

Why: If the crown on the implant has broken or your not happy with the esthetics its better to just replace the crown as the fee would be similar to a veneer

No: veneers are made of 0.3-0.5 mm porcelain layer The implant has a full coverage porcelain crown and veneers would not work.

Definitely, No: Veneers cover chips, gaps, and stains, while implants replace missing teeth and are restored with crowns or dentures.
