Charcoal Teeth Whitening Strips My Brilliant Smile Our teeth whitening strips based on activated charcoal with the addition of coconut oil are designed as an alternative to hydrogen peroxide-based strips that damage tooth enamel and cause pain and are even banned in the EU countries. Our strips do not contain hydrogen peroxide or carbamide peroxide. Active components are bicarbonate sodium and activated carbon. These components are an excellent alternative for people with increased sensitivity of teeth, who want to get no less good results than after hydrogen peroxide, but without any health risks.
