Solid effervescent compositions are described. The solid compositions include an edible acid and a carbonate salt (e.g., sodium carbonate or sodium bicarbonate). The compositions can further include one or more water soluble functional ingredients. The solid compositions can be free of insoluble particulate material so as to prevent damage to the teeth or gums. The composition can be slightly acidic to assure complete dissolution and so that its flavor does not become salty. The solid compositions can be dissolved in water to form a solution having an osmolality of 310 mOsm/kg of water or less. The resulting solution can then be contacted with the oral tissues of a user. Alternatively, the solid composition can be placed directly into the oral cavity of a user and allowed to dissolve and effervesce in the oral cavity.

L'invention concerne des compositions effervescentes solides. Ces compositions solides renferment un acide comestible et un sel de carbonate (par ex., du carbonate de sodium ou du bicarbonate de sodium). Lesdites compositions peuvent, également, contenir au moins un ingrédient fonctionnel soluble dans l'eau. Ces compositions solides peuvent être exemptes de matière particulaire insoluble, afin de prévenir des dommages au niveau des dents ou des gencives. La composition peut être légèrement acide afin de garantir une dissolution totale et que sa saveur ne devienne pas salée. Lesdites compositions solides peuvent être dissoutes dans l'eau en vue de former une solution possédant une osmolalité maximale de 310 mOsm/kg d'eau. La solution résultante peut, alors, être mise en contact avec les tissus buccaux d'un utilisateur. En outre, la composition solide peut être placée directement dans la cavité buccale d'un utilisateur et amenée à se dissoudre et entrer en effervescence dans la cavité buccale.
