Desensitizing Toothpaste Desensitizing toothpastes work by blocking transmission of sensations through the tubules of the dentin layer so that they are unable to reach the nerve. It is also advised to place a small amount of desensitizing toothpaste on the sensitive areas in addition to regular brushing with it. After application, the toothpaste should be left overnight to take its effect. Consistent overnight use should bring some relief within a few weeks.
