Sensodyne
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].
