Abstract
The present invention is a method for desensitizing and thereby relieving the pain and discomfort that often accompanies sensitive teeth in humans. A desensitizing agent in the form of a toothpaste, gel or mouthwash is applied to the surface of the teeth and physically forced into the dentinal tubules responsible for the sensitive condition using a flexible rubber or plastic applicator in the form of a cylindrical or rectangular post or block, preferably with an upper surface in the form of a recessed indentation, serrated surface or concave-shaped cup.
