1. The quick answer
Yes — you can absolutely whiten your teeth while wearing clear aligners or retainers, as long as you’re using an enamel-safe, dentist-approved gel like Expertwhite 35% Carbamide Peroxide Gel.
In fact, whitening during your aligner treatment can be one of the most effective and convenient ways to brighten your smile.
The aligners act like custom whitening trays — holding the gel snugly against the teeth for deep stain removal.
2. Why whitening with aligners works so well
Aligners (like Invisalign or ClearCorrect) are made from a smooth, close-fitting plastic that forms an airtight seal around your teeth.
That makes them perfect for holding whitening gel exactly where it’s needed.
When paired with a professional-grade formula like Expertwhite 35% Gel, this combo delivers:
-
Even whitening coverage (front and between teeth)
-
Faster results thanks to consistent contact time
-
No messy trays — your aligners are the trays
-
No sensitivity due to Expertwhite’s near-neutral pH balance
“My go-to! For white and bright teeth!” — Hannah K., Expertwhite customer
3. How to whiten safely with aligners or retainers
Step-by-step:
-
Clean your aligners thoroughly (no soap or toothpaste residue).
-
Apply a tiny bead of Expertwhite 35% Carbamide Peroxide Gel inside each aligner (front surface area only).
-
Insert aligners and wear for 30 minutes (or up to 1 hour for deeper whitening).
-
Remove, rinse thoroughly, and brush gently.
-
Repeat daily for 5–7 days for visibly whiter teeth.
💡 Tip: Avoid eating or drinking for 30 minutes after whitening.
4. Whitening after finishing Invisalign
Once you’ve completed your Invisalign or aligner treatment, whitening can help remove residual stains that built up during wear.
Two great options:
-
Expertwhite Prefilled Trays (BrightGlo Max): Perfect for fast 30-minute whitening with dentist-grade hydrogen peroxide.
-
Expertwhite Max HP Foam: Ideal for cleaning your new retainers daily while maintaining a fresh white glow.

6. What to avoid when whitening with aligners
🚫 Don’t use whitening toothpaste inside aligners — it’s abrasive.
🚫 Avoid gels not labeled as aligner-safe — some cheap formulas are acidic and can damage trays.
🚫 Don’t leave gel in overnight unless using a slow-release carbamide peroxide like Expertwhite 35% CP.
7. Whitening maintenance after aligner treatment
Once your aligner journey ends, maintain your results effortlessly:
-
Daily: Use Expertwhite Max HP Foam to clean retainers and refresh brightness.
-
Every 3–6 months: Touch up with Expertwhite Prefilled Trays or Gel.
-
As needed: Use Expertwhite Pen for quick touch-ups after coffee or wine.
