Dental desensitizing solutions and methods of using the solutions are disclosed. The solution may include 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. The solution may include a solubility enhancer, the solubility enhancer increasing the solubility of the active ingredient in the solution. The active ingredient may be oxalic acid, potassium salt dihydrate and the solubility enhancer may be sodium hydroxide, however, other active ingredients and solubility enhancers are disclosed. The solution may be applied to the tooth dentin and/or cementum to reduce hypersensitivity or pain from certain stimuli. The solution may increase the solubility of the active ingredient by at least 1.0 g/L at a given temperature. The solution may include at least 0.3 g/L of the solubility enhancer.

A biocompatible composite material for controlled release is disclosed, comprising a biocompatible metal oxide structure with a loaded network of pores. The pore network of the biocompatible composite material is filled with a uniformly distributed biologically active micellizing amphiphilic molecule, the size of these pores ranging from about 0.5 to about 100 nanometers. The material is characterized in that when exposed to phosphate-buffered saline (PBS), the controlled release of the active amphiphilic molecule is predominantly diffusion-driven over time.
