Frequently Asked Questions

Read All FAQ
What is the difference between Opal Classic Prefilled Whitening Trays and Opal Gentle Prefilled Whitening Trays?

Our Gentle formula contains a lower hydrogen peroxide content (only 6%) compared to our Classic formula (11%), making it perfect for even the most sensitive smiles. If you’re concerned about sensitivity but still looking to safely brighten your smile, our Gentle Prefilled Whitening trays are made especially for you!

Are Opal Prefilled Whitening Trays the same as Opalescence Go Prefilled Whitening Trays?

No. While both Opal™ Prefilled Whitening Trays and Opalescence Go™ Prefilled Whitening Trays are very effective at whitening teeth, they have a few key differences. 

  • Only available through your dentist, Opalescence Go™ Prefilled Whitening Trays are professional grade trays containing potassium nitrate and fluoride to provide extra comfort. 
  • Opal™ Prefilled Whitening Trays feature two formula strengths: Classic (11% hydrogen peroxide) and Original (6% hydrogen peroxide) to suit your comfort level, and can be easily ordered online for convenient, at-home teeth whitening.
Do Opal Prefilled Whitening Trays provide the same results as professional whitening treatments?

Many people notice quick, visible results—up to 4-5 shades whiter1—after using Opal™ by Opalescence® Prefilled Whitening Trays. That being said, everyone responds differently to teeth whitening treatments and everyone’s teeth whiten at different rates. Some stains are easier to treat than others. Yellow or brown teeth are easier to whiten than gray-ish teeth. Even age can impact the rate at which your teeth whiten! If in doubt, we recommend you visit your dentist for a pre-whitening consultation, so that they can help you make the right choice.

Do I need to see my dentist before I use Opal Prefilled Whitening Trays?

No. However, if you have pre-existing sensitivity when it comes to your teeth, we recommend consulting your dentist before using any teeth whitening products.

Do I need impressions or molds to use Opal Prefilled Whitening Trays?

Not at all! Opal™ by Opalescence® Prefilled Whitening Trays use the heat from your mouth to conform to your teeth for a perfect fit that keeps you comfortable while you brighten your smile.

Can I reuse my Opal Prefilled Whitening Trays with Whitening Gel Refills?

No. Opal™ Prefilled Whitening Trays are designed for one-time use. Once you’ve finished brightening your smile with your trays, go ahead and discard them.

Do I need to brush my teeth before I use Opal Prefilled Whitening Trays?

We recommend giving your teeth a quick scrub with Opal™ by Opalescence® Original or Sensitivity Relief Toothpaste after using your prefilled whitening trays.

Can I use Opal teeth whitening products with crowns, veneers, fillings or other dental work?

Yes! It’s safe to use our teeth whitening products on both natural and unnatural tooth surfaces. Our unique formulations will not affect the color or shade of a crown, veneer, implant, filling or tooth restoration. But, you can use our products to whiten your natural teeth to better match your dental work.

If you are whitening your teeth before a bonding procedure, talk to your dentist. We recommend avoiding any whitening treatments for 7–10 days before a bonding procedure.2-4
