Will veneers at a young age lead to implants or partials earlier?

No necessarily. : If good oral hygiene is practiced, there should be no reason why teeth with veneers will be any more susceptible to failure than normal teeth. Again the key is how the veneers are taken cared of.

No: With proper hygiene , well placed veneers should not affect the life of the tooth in most circumstances.

Shouldn't: If done properly and well maintained, there should be absolutely no relation between veneers and earlier partials/implants. Think preserve what you have, not plan to replace later ! good luck.

See answer: All dental work is like a bandaid. When you first get a filling, it's a small bandaid. If that has trouble or new decay, then the filling is bigger. Bigger bandaid. If that then fractured or has recurrent cavities then you get a crown - bigger bandaid. All the way up to a root canal or losing a tooth. Any dental work must be taken care of carefully with brushing and flossing.
