Abstract:
1. A composition that is a toothpaste, a tooth powder, a prophylaxis paste, a lozenge, a gum or an oral gel, for reducing dentinal hypersensitivity and remineralizing exposed dentinal surface and open dentinal tubules, comprising a desensitizing amount of a desensitizing/remineralizing agent in a non-aqueous carrier which is formed in situ upon contact with saliva when applied to an oral cavity, wherein said desensitizing/remineralizing agent consists essentially of a water soluble calcium salt and a water soluble silicate selected from lithium silicate, sodium silicate, potassium silicate or ammonium silicate, or mixtures thereof, which would otherwise react with the calcium salt in an aqueous carrier, and wherein said calcium salt reacts with said water soluble silicate upon contact with the saliva forming said desensitizing/remineralizing agent in situ for remineralizing exposed dentinal surface and open dentinal tubules.
