The short version
Whitening products only work on natural tooth structure. Veneers, crowns, and bonding don't respond to peroxide. But that doesn't mean whitening is off the table if you have dental work. You just need to approach it in the right order.
Veneers
Porcelain veneers are custom-colored during fabrication and don't change shade afterward. No whitening product will make a veneer lighter or darker.
What to do: If you're planning veneers, whiten your natural teeth first. Get them to your desired shade, then have veneers fabricated to match. This way everything blends. If you already have veneers, you can still whiten the natural teeth around them, but talk to your dentist about shade matching first.
Crowns
Same principle as veneers. Porcelain and ceramic crowns don't respond to whitening products. Whiten your natural teeth first, then have crowns made or remade to match.
Dental bonding (tooth-colored fillings)
Composite resin bonding does not whiten. If you have bonding on your front teeth and you whiten the surrounding natural tooth, you may end up with a visible mismatch. The natural tooth gets lighter while the bonding stays the same shade.
Solution: Whiten first, then have the bonding touched up to match your new shade. Composite bonding is relatively inexpensive to redo.
Metal braces
You can whiten with braces, but it's challenging. The brackets block the whitening gel from reaching the tooth surface underneath, which means you'll get uneven results (lighter between brackets, darker behind them).
My recommendation: Wait until braces come off, then whiten. Your teeth will whiten evenly, and your orthodontist will love you for not complicating things. If you want to manage staining during treatment, use whitening toothpaste and rinse after meals.
Invisalign and clear aligners
Clear aligners are actually an advantage for whitening. Remove your aligners, apply whitening gel, use your LED mouthpiece for 10 minutes, rinse, and reinsert your aligners. The aligners themselves can act as a barrier to keep gel on your teeth (though I recommend using the LED mouthpiece for proper light activation).
Timing tip: Whiten right after switching to a new set of aligners. Your teeth are slightly looser during transitions, which means the gel can reach more surface area.
Implants
Dental implant crowns are made from porcelain or zirconia. Like veneers and crowns, they don't respond to whitening. Whiten your natural teeth first, then have implant crowns shade-matched.
The golden rule
If you're planning any cosmetic dental work (veneers, crowns, bonding, implants), always whiten first. Get your natural teeth to the shade you want, wait 2 weeks for the color to stabilize, then have your dental work fabricated to match. Doing it in the wrong order means either living with a mismatch or paying to redo the dental work.
