Acid resistant composition having improved solubility

A method of decreasing tooth sensitivity, comprising:

• applying a solution including an active ingredient and a solubility enhancer including sodium hydroxide (NaOH) to the tooth, the active ingredient being configured to react with calcium in the tooth to produce a plurality of acid-resistant crystals that at least partially occlude dentinal tubules in the tooth and the solubility enhancer being configured to increase the solubility of the active ingredient in the solution.

The method of 12, wherein the solubility enhancer increases the solubility of the active ingredient to at least 26 g/L at 20° C.

A dental desensitizing solution comprising:

• an oxalic acid, potassium salt dihydrate;
• and a solubility enhancer;
• wherein the solubility enhancer increases the solubility of the oxalic acid, potassium salt dihydrate in the solution to at least 26 g/L at 20° C.

A dental desensitizing solution comprising:

• an active ingredient, the active ingredient, when applied to a tooth, being configured to react with calcium in the tooth to produce a plurality of acid-resistant crystals that at least partially occlude dentinal tubules in the tooth;
• and a solubility enhancer containing at least one member from the group of alkali metal hydroxides, alkaline earth metal hydroxides, and mixtures thereof.

A method of decreasing tooth sensitivity, comprising:

• applying a solution including an active ingredient and a solubility enhancer to the tooth, the solubility enhancer selected from at least one of alkali metal hydroxides, alkaline earth metal hydroxides, and mixtures thereof, the active ingredient being configured to react with calcium in the tooth to produce a plurality of acid-resistant crystals that at least partially occlude dentinal tubules in the tooth and the solubility enhancer being configured to increase the solubility of the active ingredient in the solution.
