There is a wide variety of commercially available bleaching systems depending on the bleaching agents used.

ProWhite 35% TOWER Whitening System comes at the price of $59.99 including 3-Syringe Pack of 35% whitening gel and is designed for home-use. This is a good system for those who tend to use a lot of bleaching gel. ProWhite uses the same active ingredient 35% Carbamide Peroxide, as those applied in the dental office. The kits includes all which is necessary to provide you with over 200 whitening sessions without purchasing additional refill gels.

All ProWhite bleaching products are based on carbamide peroxide, only the concentration of the bleaching gels is different. The ProWhite 22% TOWER Whitening System and the ProWhite 16% TOWER Whitening System promise the same results and the same number of applications so the choice of the customer is brought to the concentration of the solution. Those who think that their teeth are more sensitive or do not need considerable whitening are welcome to use the lighter solutions. Both 22% and 16% solutions come at similar prices as the stronger 35% solution.

All the kits provide bleaching trays, professional tooth shade guide, dental whitening handbook and detailed instructions for use. With these products, each application of bleaching gel requires about 1 ml per dual-arch application and the mouthpiece should be worn during an average of one hour per application. If you use less gel, you can prolong the time you wear the mouthpiece. Besides, if you already have mouthpieces and need only bleaching gel, you can buy the 16% solution which is sold separately.
