What Causes Tooth Sensitivity Pain?

Sensitivity pain occurs when the softer inner layer of the tooth, called dentin, becomes exposed—revealing small holes, or tubules. When you eat hot or cold foods and drinks, they can reach the exposed dentin tubules and trigger the nerves inside your teeth, causing a short, sharp pain.



Sensodyne Rapid Relief Ingredients

Sensodyne Rapid Relief includes an active ingredient called stannous fluoride. The formulation quickly builds a layer over exposed dentin. After the first brush, it starts to form a protective barrier that quickly blocks the tiny holes in the sensitive areas of your teeth. It provides clinically significant sensitivity pain relief in 60 seconds and long lasting protection with twice daily brushing. Plus, it provides the benefits of a regular toothpaste, like cavity protection and breath freshening, to help you maintain a healthy mouth.
