Toothpaste の説明 from Sensodyne
What are sensitive teeth?
Lots of people have sensitive teeth. When enamel is worn away (through eating everyday acidic food or drinks) or gums recede, the dentin underneath becomes exposed. This can lead to tooth sensitivity, for example, with cold and hot food and drinks.
What does Sensodyne do?
Sensodyne provides daily care for sensitive teeth plus all the benefits you would expect from a daily fluoride toothpaste - strong teeth and freshness.
