What is Carbamide Peroxide?

Carbamide peroxide active ingredient in whitening gels. It is the most commonly used whitening gel for at-home teeth whitening purposes. Carbamide peroxide whitening gels come in different strength. The most common concentrations sold and used are 16%, 22% and 35%. We recommend our 22% whitening gel for most teeth whitening applications. Gels with 35% concentration act faster. With these gels whitening application should not be more than 30 minutes per treatment. The 22% concentration allows for longer treatment and deeper penetration into your teeth surface. Thus over a longer time period these gels may be more effective then stronger gels.

Carbamide peroxide gels can be stored for longer time periods. Usually for about 2 years. Thus these gels are better fitted for at-home teeth whitening as they can be sold, shipped and stored without loss of strength.
