The root of the tooth, or the [[dentin]], is made up of microscopic "tubules" or pores. In some people, the root becomes exposed because of gum recession or [[gingivitis]]. Because the tubules are porous, hot and cold sensations (from hot or cold foods or drinks) can reach the nerve endings easily; the nerves fire, causing a sensation of pain or sensitivity. |
|||
Sensodyne works because the potassium ions and fluoride penetrate the dentinal tubules and depolarize the nerve, which blocks pain transmission. According to Nickolson (2007), “a dentifrice for desensitizing dentinal hypersensitivity needs to be used for at least two weeks to have an effect, and continued use is needed to avoid relapse” (p. 88). |

Sensodyne is a brand of toothpaste marketed for individuals with sensitive teeth[1] and/or dentine hypersensitivity. It is a registered trademark of GlaxoSmithKline which acquired it in 2001 in the purchase of Block Drug which developed it.[2]
Sensodyne has two main product lines: sensitivity and acid erosion[3]. Sensodyne sensitivity products are marketed to counteract teeth sensitivity caused by exposed dentin. The active ingredient, Potassium nitrate[3], is claimed to form a protective barrier in the tooth. Clinical studies have found that potassium nitrate may be effective in treatment of dentine hypersensitivity[4]. Sensodyne acid erosion products, Sensodyne ProNamel, are marketed to protect enamel from acid erosion. One of ProNamel's active ingredients, fluoride[5], is widely endorsed to make teeth more resistant to acid attacks and to repair previous acid decay[6]. Both products come in a variety of flavours and with the option of whitening[3].
