Our Pre-Loaded Tray Kit is a professional teeth whitening kit that’s gaining in popularity among non-dentists because of its ease of use and good results. It’s perfect for teeth whitening kiosks. Because non-dentist teeth whitening specialists are not allowed to apply whitening gel, that leaves it to the customer to apply the gel. With our Pre-loaded Tray Kit, the customer simply places the tray in their mouth – nothing could be faster and easier for both the technician AND the customer. The drawback is that our most effective whitening gel for non-dentists (16% hydrogen peroxide) cannot be used with mouth trays, so the results, although good, are not as good as they are with our paint-on system. We offer this kit with up to 44% carbamide peroxide gel or low-concentration hydrogen peroxide gel. The Pre-Loaded Tray Kit is also perfect for customers who have highly sensitive teeth because it contains our gentlest peroxide gel for professional whitening.
