1. A chewable composition for teeth-whitening, comprising a first and a second region separated by a barrier layer,
the first region comprising an anhydrous chewing gum base having water content of about 1% or less, an anhydrous fruit acid, carbamide peroxide having water content of about 2% or less, and one or more gum additives, wherein, the ratio of gum base:carbamide peroxide:fruit acid, in percent weight relative to the first region, is about 10-50:1-20:0.5-8, and the one or more gum additives are present in an amount sufficient to reach 100% of the weight of the first region; and
the second region comprising a chewable composition comprising a source of bicarbonate ion, a gum base, and one or more gum additives,
wherein the source of bicarbonate ion and the gum base, respectively, are present in a ratio of about 5-30:15-50 in percent weight relative to the second region, and the one or more gum additives are present in an amount sufficient to reach 100% of the weight of the second region, wherein the source of bicarbonate ion is sodium bicarbonate and the ratio of fruit acid:carbamide peroxide:sodium bicarbonate, by mass, is about 0.5-5:5-30:15-45.
