## Features

- CUSTOM-FIT SEAL FOR CLEANER WHITENING: These thermoform dental trays soften in hot water and mold around your teeth for a personalized fit in minutes. The snug seal helps keep whitening gel against enamel instead of leaking onto gums, supporting more even coverage with less mess during treatments.
- 4 TRAYS INCLUDED FOR STRESS-FREE MOLDING: Most whitening tray kits include only two trays. Cool Teeth Whitening includes four reusable moldable trays so you have extra attempts if your first fit is not perfect, plus backups for future whitening sessions or replacement use over time.
- SLIM FLEXIBLE DESIGN FOR BETTER COMFORT: Unlike bulky sports guards or rigid one-size trays, these thin BPA-free whitening trays flex naturally around teeth for a lighter, more comfortable feel. The trim-to-fit edges help reduce rubbing against gums while supporting a secure fit during wear.
- WORKS WITH YOUR EXISTING WHITENING ROUTINE: Compatible with carbamide peroxide and hydrogen peroxide whitening gels, these custom dental trays work with popular systems including Opalescence and Philips Zoom. Ideal for replacing lost trays or upgrading from whitening strips that slide during use.
- HYGIENIC STORAGE FOR HOME OR TRAVEL: Includes two ventilated black retainer cases that help reduce moisture buildup between whitening sessions. The breathable design keeps trays protected, organized, and ready for travel or daily storage as part of a cleaner whitening routine.
- Even Gel Distribution for Better Whitening Results
- Compatible With All Whitening Gels: Our dental whitening trays work with popular whitening gels including carbamide peroxide and hydrogen peroxide formulas. Fully compatible with Opalescence, Philips Zoom, and most teeth whitening gel systems. (Whitening gel not included.)
