SnF2 and KNO3: Stannous Fluoride is tin Fluoride and is used to fight cavities. Forty subjects were included in the study. But, it will take several uses before you start feeling the difference. Potassium Nitrate blocks pathways from the tooth surface to the inner pulp, protecting the tooth's nerves and effectively desensitizing them to reduce discomfort. Major uses of potassium nitrate are in fertilizers. By blocking dentinal tubules; this prevents stimuli (e.g., cold drink or air) from causing fluid flow in dentinal tubules, thereby preventing nerve pain inside the tooth from being stimulated. In addition, Leonard et al. Myth #4 – Stannous Fluoride does not work as well as Trisoclan for antibacterial benefits. Fluoride strengthens weak or eroded enamel and helps to prevent the early signs of tooth decay from progressing. Potassium nitrate is a chemical compound with the formula kno3. Participants were not allowed an additional oral hygiene aids such a floss or interdental stimulators. They quite different in use and in their chemical composition. Potassium nitrate and stannous fluoride are two commonly found desensitizing agents in toothpastes. Sensodyne toothpastes contain 1 of 2 ingredients: Potassium Nitrate or Stannous Fluoride. Potassium nitrate will work just as well as strontium chloride in terms of reducing your sensitivity, so my recommendation is this – just go with the safer active ingredient: potassium nitrate. 3 They work via different mechanisms; the potassium ions in potassium nitrate help to reduce sensitivity by depolarizing the nerve cells 4 while stannous fluoride acts to reduce sensitivity by occluding the dentinal tubules with a tin-rich surface deposit. SnF2 and KNO3: Stannous Fluoride is tin Fluoride and is used to fight cavities. All Sensodyne products contain fluoride, which helps fight against cavities, so you can maintain healthy teeth every day. POTASSIUM NITRATE Helps Soothe Tooth Sensitivity Pain. Fluoride. determined whether the daily use of an active desensitizing agent (Ultra EZ” 3% potassium nitrate and 0.11% by weight fluoride ion) during night guard tooth whitening would decrease tooth sensitivity in a population at risk for tooth sensitivity when compared with a placebo. Potassium nitrate is a common nerve desensitizing agent and stannous fluoride is popular agent that reduces sensitivity by occluding dentinal tubules. It is a chemical compound with the formula snf2. Potassium toothpaste (5% potassium nitrate and 1450 ppm fluoride) and mouthwash (0.51% potassium chloride and 230ppm sodium fluoride, in an alcohol base) Control toothpaste (1450 ppm fluoride) and arginine and potassium free mouthwash. It is a chemical compound with the formula snf2. Potassium nitrate is a common nerve desensitizing agent and stannous fluoride is a popular agent that reduces sensitivity by occluding dentinal tubules. If you suffer from severe sensitivity, stannous fluoride is your best bet for getting relief.
