Behind the Paste: Sensodyne
Ingredients & How They Work

Not all toothpastes provide relief for people with tooth sensitivity. Sensodyne is specifically made to help relieve and protect against sensitivity,* deliver cavity protection, and leave behind a fresh taste. Here’s a look at three ingredients found in different Sensodyne products and how they work to protect sensitive teeth so you can enjoy the things you love with confidence.

Potassium Nitrate Helps Soothe Sensitivity Pain

Potassium nitrate helps prevent the nerves in your teeth from sending pain signals—triggered by certain stimuli, like hot coffee or ice water—to your brain. It is known as a nerve-calming ingredient.

Stannous Fluoride and NovaMin Builds a Protective Layer

Stannous fluoride acts to build a protective barrier over the sensitive areas of your teeth. This layer helps prevent stimuli, like hot and cold liquids, from reaching the nerves and causing pain. Sensodyne Complete Care and Sensodyne Rapid Relief contains Stannous fluoride. Sensodyne Repair and Protect contains NovaMin.

Fluoride Protects Tooth Enamel 

Fluoride is a mineral that helps strengthen tooth enamel to help prevent tooth decay. Once enamel is worn down, the dentin layer underneath becomes exposed and more susceptible to sensitivity. Sensodyne toothpastes contain sodium fluoride or stannous fluoride.

With formulations specifically designed to provide lasting* protection and sensitivity relief, Sensodyne is the #1 brand for sensitive teeth**.
