Sensodyne is a brand name of toothpaste and mouthwash targeted at people with sensitive teeth.[1] Sensodyne is owned by Haleon and is marketed under the name Shumitect in Japan.[2]
Effectiveness and ingredients
Sensodyne toothpastes work in different ways depending on the product's active ingredient—potassium nitrate, strontium acetate/chloride.
Potassium nitrate
The potassium ion hyperpolarizes[3] the nerve and stops it from firing. The nerve impulses are thus desensitized and there is no pain.
