When you get porcelain veneers, you want them to last. They're beautiful pieces of dental work, and it's natural that you want to enjoy them for as long as possible.
Fortunately, veneers do a lot of their own maintenance work. They're strong and durable, and they are firmly bonded to your teeth. As such, they can be expected to last for at least a decade.
Of course, veneers aren't completely self-maintaining. You have to take care of them as well. The good news is that maintaining your porcelain veneers is really quite simple.
