Designed for people who already use whitening gels, replacement seekers, and first-time DIY users, these custom-fit trays help improve gel placement while reducing slipping, mess, and wasted product. Using thermoform material that softens in hot water, each tray molds around your unique tooth shape for a more personalized fit in just minutes. The snug seal helps keep whitening gel evenly positioned against teeth while reducing overflow onto gums that can cause irritation during whitening sessions. Unlike bulky one-size mouth trays, these slim BPA-free dental trays are designed for everyday comfort. The flexible material adapts naturally to your smile and can be trimmed for a more precise fit, helping reduce jaw fatigue and improving wearability during longer treatments or overnight use. The included 4-tray system provides added peace of mind during molding. If your first fit is not perfect, you still have extra trays available for remolding, future whitening maintenance, or replacement use later on. This makes the kit especially helpful for beginners who want a simple, repeatable whitening process without the pressure of getting everything right on the first attempt. To support a cleaner routine, the kit also includes 2 ventilated black storage cases that help trays dry properly between uses. The compact design keeps your trays protected and travel-ready while reducing moisture buildup inside the case. Compatible with all major whitening gel systems, including carbamide peroxide and hydrogen peroxide formulas, these trays work seamlessly with brands such as Opalescence and Philips Zoom. Simply pair them with your preferred whitening gel, LED light, or whitening pen to build a flexible at-home whitening system that fits your routine. Whether you are replacing old trays, upgrading from whitening strips, or building a more organized whitening setup, Cool Teeth Whitening provides a reusable custom-fit solution designed for comfort, convenience, and long-term value. Whitening gel not included. ## 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.
