What Is in Sensodyne?

Sensodyne toothpastes contain 1 of 2 ingredients: Potassium Nitrate or Stannous Fluoride.

All Sensodyne products contain fluoride, which helps fight against cavities, so you can maintain healthy teeth every day.

Code for potassium nitrate, which helps sooth sensitivity pain

POTASSIUM NITRATE Helps Soothe Tooth Sensitivity Pain

Sensodyne toothpastes with potassium nitrate soothe the nerves inside your teeth, preventing them from sending pain signals from triggers, like a burst of cold air or hot coffee.

Sensodyne Essential Care toothpastes (aside from Sensodyne Deep Clean) and Sensodyne True White toothpastes do not have SLS (sodium lauryl sulfate), an ingredient that makes toothpaste foamy when you brush, but can also irritate sensitive teeth and gums.

Code for stannous flouride, which builds a protective layer around the tooth

STANNOUS FLUORIDE Builds a Protective Layer

Sensodyne toothpastes with stannous fluoride work like a shield to protect the exposed soft, inner part of the tooth called dentin. This shield helps prevent triggers, like a cold soda, sweets, or sour candy, from reaching the nerves inside the tooth and causing pain.
