Buying Guide: Key Considerations For Trays And Gels
- Tray material: Look for BPA-free, food-grade silicone or thermoform plastics for comfort and safety. Moldable trays are preferred by those who want a custom seal with gel.
- Fit and customization: Moldable trays require hot-water shaping. Ensure the tray is easy to mold and remains stable during whitening sessions.
- Gel strength: Higher concentrations (like 44% carbamide peroxide) offer faster results but can increase sensitivity. Beginners may prefer lower-percentage gels with longer treatment times.
- Hygiene and storage: Trays with included ventilated cases reduce contamination risk between uses. Cleaning instructions should be straightforward and clear.
- Convenience: Prefilled, all-in-one bundles reduce setup time and are travel-friendly, but may limit customization compared to fill-your-own-gel trays.
- Compatibility: If you already own LED kits or syringes, verify gel compatibility with your existing system to maximize results and minimize waste.
