Philips Zoom 16% Nite White Carbamide Peroxide Teeth Whitening Gel Complete Kit | 6 x 2.4gram Syringes | Zipper Bag & Mouth Tray Case Included

16% carbamide peroxide currently gives me the best results with the low sensitivity for night time whitening. This gel can be used in your aligners, whitening trays or clear retainers. If you don’t have these then I would suggest buying the plastic thermoformed trays to use for your whitening.
