An aqueous oral care fluoride treatment composition, a method of providing fluoride to a patient's tooth surface, and a method of reducing the incidence of dental caries, wherein the composition includes: 0.1 wt-% to 3.0 wt-% of a crosslinked poly acid having carboxylic acid side groups; a pharmaceutically acceptable buffer; 1.0 wt-% to 2.5 wt-% of sodium fluoride; 0.025 wt-% to 1.75 wt-% of a multivalent cation salt; and at least 60 wt-% water; wherein the weight percentages are based on the total weight of the aqueous composition.

Aqueous oral care fluoride treatment compositions, and methods

An aqueous oral care solution, a kit that includes such solution, a method of making such solution, a method of using such solution (e.g., a method of providing fluoride to a patient's tooth surface), and a tooth surface having a coating derived from the aqueous oral care solution, wherein the oral care solution includes: silver cations; thiocyanatc anions provided by a thiocyanatc source comprising Ca(SCN)2; fluoride anions; and water; wherein the molar ratio of silver to thiocyanatc ions is up to 0.40:1, and water is up to 57 wt-%, based on the total weight of the solution.

Aqueous oral care solutions, methods, kits, and tooth surfaces having a coating derived from the oral care solution

Disclosed herein a dental mill blank and a method of forming the dental mill blank. The dental mill blank includes a first layer of a first hard restorative material having a first translucency and a first shade, a second layer of a second hard restorative material having a second translucency and a second shade, where at least one of the following is true (1) the first translucency is different from the second translucency, (2) the first shade is different from the second shade. The first layer and the second layer form a first interface having a first curve across a first plane of symmetry of the dental mill blank, where the first curve has a different from zero curvature; and a first straight line along the entire length of a second plane of the dental mill blank, the second plane being orthogonal to the first plane of symmetry.
