The Science Behind Sensodyne Rapid Relief Toothpaste
What Causes Tooth Sensitivity?
Tooth sensitivity occurs when the softer inner layer of the tooth, called dentine, 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, sensation.
Sensodyne Rapid Relief Ingredients
Sensodyne Rapid Relief includes an active ingredient called Strontium Acetate. This formulation quickly builds a layer over exposed dentine. 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 significant protection from tooth sensitivity and ongoing 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.
