Rapid Relief Whitening Toothpaste の説明 from Sensodyne
What is tooth sensitivity?
Sensitivity occurs when the dentin underneath tooth enamel becomes exposed. When exposed dentin comes into contact with hot or cold, sweet or sour, or even your toothbrush, it can trigger the nerve causing a short, sharp pain.
Sensodyne Rapid Relief is clinically proven for fast relief of sensitivity pain.
Its formula quickly creates a barrier over sensitive areas of your teeth to provide fast relief, and to help stop the pain from coming back. With twice daily brushing, it builds ongoing protection from the pain of sensitive teeth. It also helps whiten enamel and prevents staining.
