I had six lower veneers. A seventh was done about three weeks later. Why are they different shades?

Why I have different color for my porcelain veneer done at different time?
Depending on the type of porcelain used, such as feldspathic which is powder and liquid, the amounts used can vary slightly, hence will give you slightly different shade and color.
The other possibility is that if the original tooth is darker than adjacent teeth, since you are adding 1/2 mm porcelain on the tooth, the underlying core color can show thru. We call it a show thru phenomenon.
In these cases prior to bonding the veneer, your good cosmetic dentist must predict that, and have custom work done by the lab technician to exactly match the color you desire. Of course there is more cost to the dentist and you, but the extra cost is well worth it, so you be happy.
Usually for any replacement of single front tooth with veneer, or a dental crown, this is a must with an expert cosmetic dentist.
Porcelain veneers should be done at the same time
This most commonly comes up when people want 8-10 veneers, but only 1-2 per year. This might make it more affordable, using dental benefits more than once, but the result is rarely satisfying. They won't be WAY off, but can be noticeable.
