Editing Strontium chloride (section)

===Dental care===
SrCl<sub>2</sub> is useful in reducing tooth sensitivity by forming a barrier over microscopic tubules in the [[dentin]] containing nerve endings that have become exposed by gum recession. Known in the U.S. as Elecol and [[Sensodyne]], these products are called "strontium chloride toothpastes", although most now use [[potassium nitrate|saltpeter]] (KNO<sub>3</sub>) instead which works as an analgesic rather than a barrier.<ref>{{cite web |url= http://www.sensodyne.co.uk/how_it_works.htm |publisher= [[Sensodyne]] |title= Sensodyne |access-date= 2008-09-05 |archive-url= https://web.archive.org/web/20080918193411/http://www.sensodyne.co.uk/how_it_works.htm |archive-date= 2008-09-18 |url-status= dead }}</ref>
