Frequently Asked Questions
What does Crest's 60-day money-back guarantee actually cover?
The guarantee applies to Crest's whitening products specifically: 3D Whitestrips, 3D Whitestrips with 3D Light, the Whitening Pen (with or without 3D Light), and the Whitening Emulsions and serums. Crest's toothpaste and mouthwash guarantee programs were sunset on June 30, 2025, so those product lines no longer qualify even though the whitening treatments still do.
How do I actually get a refund under the Crest money-back guarantee?
Customers submit an electronic guarantee request within 60 days of the original purchase, including proof of purchase showing the date, price, retailer name, and product, plus the UPC barcode from the packaging. Refunds come back as a prepaid debit card rather than cash to the original payment method, and Crest states to allow 6 to 8 weeks for delivery.
Is there a limit to how many times I can use the Crest whitening guarantee?
Yes. It's limited to one refund per name, household, or address over a lifetime, and using multiple addresses or PO boxes to get around that limit counts as fraud under Crest's terms.
Does the Crest whitening guarantee work if I bought from a discount or resale site?
No. Because Crest can't verify product quality from unauthorized sellers, the guarantee excludes purchases made through unauthorized internet sites, so it's safest to buy through Crest's own site or a recognized retailer like Amazon, Walmart, Target, CVS, or Walgreens if keeping the guarantee available matters.
Where does Crest ship whitening orders placed directly through its site?
Orders only ship to addresses within the contiguous 48 states or the District of Columbia, and Crest only accepts payment from U.S. billing addresses, so anyone outside that footprint needs to buy through a retailer that ships to their location instead.
Can I stack a Crest White Smile coupon code with the money-back guarantee?
Yes, they're independent of each other. A coupon reduces what's paid at checkout, while the guarantee is a separate 60-day satisfaction window tied to the purchase price actually paid, so using a code first doesn't affect eligibility for the guarantee later.
Which Crest whitening product should I buy if I want the fastest results?
3D Whitestrips with 3D Light and the Whitening Pen with 3D Light are built around faster treatment cycles than the standard strips or the Whitening Emulsions, which is worth factoring in against the price difference before choosing which kit a coupon code gets applied to.
