I have had a veneer on a front tooth for about 20 years. The dentist etched the surface and stuck on the veneer. It has been great until this week. The problem is not the veneer. The underlying tooth has had a root canal for over 40 years? The tooth itself has snapped off. I don't know if there is enough to get capped or if I am looking at a bridge.
As long as the dentist has a good reputation for doing quality dental work, you shouldn't have a problem. Ask if you can see an example of the veneer size in a mirror before you commit to the process. As another board member said, you don't want to look like Bugs Bunny.
