If you are thinking to have porcelain veneers, it is best to have them all done in one time.
The reason being:
You will have less time in the dental chair.
the color and shape of your porcelain veneers will be matched far better!
You will not be needing a custom dental work for each veneer, consequently not absorbing further cost of color and shape matching by your cosmetic dentist.
In a nut shell do not do your dental veneers one at a time. You will not be happy.
