The present disclosure generally provides the use glucosylated natural steviol glycosides (GSGs) to reduce certain undesirable taste notes common to oral care products. In related aspects, the disclosure provides compositions that comprise GSGs and one or more ingredients that give rise to certain undesirable taste notes. In some embodiments, such compositions are in the form of a food product, a beverage product, or an oral care product, such as a toothpaste, a mouthwash, a tooth-whitening composition, and the like.

A chewable composition for teeth-whitening comprising a first region and a second region separated by a barrier layer; the first region comprising carbamide peroxide having water content of about 2% or less, a wetting agent (e.g., glycerin), an anhydrous chewing gum base having water content of about 1% or less, an anhydrous fruit acid, and one or more gum additives; and the second region comprising a chewable composition comprising a gum base, a source of bicarbonate ion, and one or more gum additives. A kit comprising separate chewable compositions corresponding to the first and second regions, and methods for whitening teeth using the chewable composition are also provided.

To provide a dental composition wherein the acid buffering capacity can be attained and the acid resistance of the tooth substance can be improved while maintaining very high foul breath inhibition capacity. A dental composition including: ion sustained-release glass; and a carrier for supporting the ion sustained-release glass, wherein the ion sustained-release glass is fluoroaluminoborosilicate glass having a composition range of: 15% to 35% by mass SiO.sub.2; 15% to 30% by mass Al.sub.2O.sub.3; 5% to 20% by mass B.sub.2O.sub.3; 20% to 45% by mass SrO; 5% to 15% by mass F; and 0% to 10% by mass Na.sub.2O.

Compositions and devices are described that provide controlled release of beneficial bacteria to the oral cavity. Such bacteria can subsequently colonize the oral cavity and displace or suppress the growth of pathogenic microorganisms. Described devices include a stabilized preparation of such beneficial bacteria and provide a consumable liquid, wet foam, or gel that includes such bacteria when used.
