Dentine hypersensitivity 5199516 196932598 2008-03-09T04:13:28Z Neparis 3900705 make external link used as reference into reference '''Dentine hypersensitivity''' is an intense pain felt when the [[dentin]] of the [[teeth]] are exposed to hot or cold foods or drinks. Pressure can also trigger the acute pain. This sensitivity can be caused by several factors, including worn or [[tooth decay|decaying teeth]] and exposed [[root canal|tooth root]]s. The rapid flow of liquids in dentinal tubules can trigger nerves along the pulpal canal of the dentin, causing pain. This hydrodynamic flow can be increased by cold, air pressure drying, sugar, sour (dehydrating chemicals), or forces acting onto the tooth. Treatment can consist of [[amorphous calcium and phosphate]], [[potassium nitrate]], [[strontium chloride]], [[gluma]], [[fluoride therapy]], or [[calcium sodium phosphosilicate]]. Potassium nitrate is commonly used in toothpastes such as Sensodyne or Crest Sensitive as a remedy. There is some dispute about their effectiveness.<ref>{{cite journal | title=Potassium containing toothpastes for dentine hypersensitivity | author=Poulsen S, Errboe M, Lescay Mevil Y, Glenny A-M | journal=Cochrane Database of Systematic Reviews | url=http://www.cochrane.org/reviews/en/ab001476.html | year=2001 | issue=2 | doi=10.1002/14651858.CD001476.pub2}}</ref> Strontium chloride is used in Sensodyne Original toothpaste. == See also == * [[Tooth]] * [[Dental pulp]] * [[Toothpaste]] ==References== {{Refimprove|date=March 2008}} <references/> == External links == * [http://www.cochrane.org/reviews/en/ab001476.html Potassium nitrate toothpaste for dentine hypersensitivity] * [http://www.ada.org/prof/resources/pubs/jada/patient/patient_33.pdf Sensitive Teeth, Causes and Treatment] [[Category:Dentistry]] {{dentistry-stub}}
