Whitening gels are received cold by the dental practice and arrive at virtually 100 percent of their original potency and effectiveness. 2. Whitening gels may be formulated with a fully aqueous base and pH at or above pH 7. 3. Without the need for chemical stabilizers, whitening gels are much more “unstable.” When placed in the warm mouth, the degradation of unstable peroxide is highly effective and thorough.16,37 3. 8. 14. 15.
