Frequently asked questions
Why does ORLA use custom trays with 6% hydrogen peroxide?
We get this question a lot—and the answer is simple: it’s the safest, most effective way to whiten your teeth. Here’s why:
Proven to Work (Even Better Than In-Office)
Clinical research shows that 6% hydrogen peroxide used in take-home trays can deliver better initial whitening results than in-office systems with higher concentrations—without compromising safety or long-term results.

Gentle on Enamel, Low Risk of Sensitivity
Studies confirm that lower concentrations like 6% hydrogen peroxide whiten effectively while dramatically lowering the risk of tooth sensitivity or soft tissue irritation.

Better Coverage, Better Control
Custom-fit trays keep the gel exactly where it should be—on your teeth. This means better whitening, less mess, and no risk of burning your gums like with strips or pens.

Results That Last
Whitening with 6% HP for just 30 minutes a day over two weeks has been shown to provide stable results that last for up to 6 months—just like in-office treatments, but without the intensity.

No Lights, No Gimmicks Despite popular marketing, light-activated whitening has no proven benefit over non-light options. ORLA skips the hype and keeps it clinical.(PMID: 30767069)
Is it safe for sensitive teeth?
Yes! ORLA was designed with sensitivity in mind. Our whitening gel uses a low concentration formula that’s gentle on enamel while still delivering professional-level results. If you’re prone to sensitivity, we recommend starting with shorter whitening sessions and gradually increasing as your comfort allows. You can also pair your whitening routine with a sensitivity toothpaste to make the experience even more comfortable.
Will it whiten crowns, veneers, or fillings?
Whitening gels like ORLA only work on natural teeth—they won’t change the color of crowns, veneers, or fillings. However, it can remove surface stains from those restorations, helping them look cleaner and blend more naturally with your smile. If you have visible dental work, we recommend chatting with your dentist about the best way to match shades.
Is ORLA safe for enamel long-term?
Yes. ORLA’s whitening gel is formulated with dentist-approved ingredients that safely lift stains without damaging your enamel. The active ingredient works only on the surface stains, leaving the natural structure of your teeth intact. When used as directed, ORLA is a safe and effective way to maintain a brighter smile over time.
Do you offer subscription refills for the gel?
Not yet, but it’s coming soon! We know whitening is something you’ll want to maintain, so we’re working on a convenient refill system to keep your trays stocked without the hassle of reordering.
