Abstract: The application relates to novel aqueous oral care compositions useful for combining and delivering incompatible stannous fluoride or stannous chloride or stannous pyrophosphate, potassium salts, and an amino acid (e.g., a basic amino acid) in a high-water composition, for example, to provide effective caries prevention, protection against dental erosion, and relief from dental hypersensitivity. Additionally, oral care compositions described here useful in order to naturally promote nitrate reduction from the oral microbiome, which can eventually result in systemic increases of nitric oxide in blood plasma, and can form part of an overall regimen to maintain or control blood pressure. Compositions comprise stannous fluoride, stannous chloride or stannous pyrophosphate, nitric acid or a water-soluble nitrate salt such as potassium nitrate, a water-soluble alkali metal polyphosphate such as tetrasodium pyrophosphate or trisodium polyphosphate, a basic amino aid such as arginine and more than 10 wt % water.

Abstract: This application relates to novel aqueous oral care compositions useful for combining and delivering incompatible stannous pyrophosphate and potassium salts in a high-water composition, for example, to provide effective caries prevention, protection against dental erosion, relief from dental hypersensitivity, and to treat or reduce malodor. The compositions comprise stannous pyrophosphate, nitric acid or a water-soluble nitrate salt, a water-soluble alkali metal polyphosphate and more than 10% water, by weight of the composition.

Abstract: The disclosure relates to oral care compositions comprising guanidine in free or orally acceptable salt form and a stannous ion source (e.g., stannous fluoride) as well as to methods of using and of making these compositions.

Abstract: This application relates to novel black translucent oral care compositions useful for combining and delivering incompatible stannous fluoride or stannous chloride and potassium salts in a charcoal composition, for example, to provide effective caries prevention, protection against dental erosion, and relief from dental hypersensitivity. The compositions comprise stannous fluoride or stannous chloride, nitric acid or a water-soluble nitrate salt, a water-soluble alkali metal polyphosphate and more than 10% water, by weight of the composition.

Abstract: Disclosed herein are oral care compositions comprising hydroxyapatite and a silica abrasive as well as methods of reducing or inhibiting enamel erosion, repairing enamel erosion damage, increasing enamel microcrack resistance and/or increasing enamel microscratch resistance using these compositions.

Abstract: In one aspect, the application relates to novel aqueous oral care compositions useful for combining and delivering potassium salts and a basic amino acid in a high-water composition, for example, to naturally promote nitrate reduction from the oral microbiome, which can result in systemic increases of nitric oxide in blood plasma and can form part of an overall regimen to maintain, reduce, treat or control systemic blood pressure.
