Frequently Asked Questions

Read All FAQ
What’s the difference between Opal Whitening Mouthwash and regular mouthwash?

One swish of Opal™ Whitening Mouthwash packs a gentle yet effective punch. Unlike many leading mouthwashes, our whitening mouthwash contains no alcohol, just the right amount of Hydrogen Peroxide to whiten teeth, and a cool, minty flavor for lasting freshness—all while being safe on enamel and brilliant on smiles.

Whether you need a quick mid-morning rinse or a pre-date confidence booster, add our new certified gluten-free, certified kosher, and vegan mouthwash to your daily oral care routine.

What results will I see from the Opal Whitening Mouthwash?

While every smile is different and results can vary, Opal™ Whitening Mouthwash safely whitens teeth and helps freshen breath as part of your daily whitening routine.

We recommend pairing Opal™ Whitening Mouthwash with our whitening toothpaste and prefilled whitening trays for the best teeth whitening results.

Does Opal Whitening Mouthwash contain alcohol?

No, Opal™ Whitening Mouthwash is 100% alcohol-free and gentle for daily use.

What flavor is Opal Whitening Mouthwash?

Cool Mint. It gives you that little burst of brilliance for lasting freshness—the perfect addition to your daily oral care routine!

Is Opal Whitening Mouthwash safe for my enamel?

Yes! All Opal™ whitening formulations are designed to promote good oral health with powerful ingredients that are gentle on enamel and gums

How long will a bottle of Opal Whitening Mouthwash last me?

It depends on how often you rinse and how much you use each time. Typically, your 15.5 oz bottle of Opal™ Whitening Mouthwash can last anywhere from 2–4 weeks if you use it daily, 1–2 times per day.

Can I use Opal Whitening Mouthwash on the same days that I use Opal Prefilled Whitening Trays, Opal Whitening Toothpaste, or my custom trays with Opal Whitening Gel Refills?

Yes! In fact, Opal™ by Opalescence® teeth whitening products are uniquely formulated to work together for maximum results. We recommend using our whitening toothpaste twice daily, rinsing with our mouthwash 1–2 times daily, and whitening with one kit (7 treatments) of prefilled trays monthly.
