Can you whiten veneers?
No. Whitening gel works by lifting stain out of natural enamel, and porcelain has no enamel to lift it from. Composite bonding does not respond either.
The shade you approve is the shade you keep. This is the whole reason whitening comes first in the sequence.
Will not lighten
Any gel, any strength, any length of time.
Keep darkening
Which is how a matched smile drifts apart over years.
The trap this creates
Say you have four veneers across the front and the rest are your own teeth. Five years later the natural ones have picked up coffee and age, and now they read darker than the porcelain.
You cannot fix that by whitening the veneers. You whiten the natural teeth back to the shade of the porcelain, then keep them there. That works, and it is the normal answer, but it does mean signing up for maintenance you should be told about before the case starts rather than after.
If your veneers look dull now
Porcelain itself holds color for years, so dullness is usually surface film, or stain sitting along the edge at the gumline, and a professional polish takes it off. Do not attack it with whitening toothpaste. Those work by being abrasive, and on porcelain that scratches the glaze, which makes it hold stain faster.
Composite bonding is a different story. Composite genuinely does discolor through the material, and once it has, the fix is repolishing or replacing it.
The order that avoids all of this
Whiten first, let the shade settle for about two weeks, then choose the porcelain against your teeth at their new color. Reverse those and you have locked your smile to the shade you happened to have on the day.
