What Causes Sensitive Teeth?
When tooth enamel wears away or gum recession occurs —either can expose the inner part of your tooth called dentine. This dentine houses thousands of microscopic channels that run toward the center of the tooth, where the nerves are.
Certain triggers like cold drinks or hot tea can cause the movement of fluid in these channels and stimulate the nerve, causing a short, sharp pain.
Sensodyne is specially formulated to relieve tooth sensitivity and is the No.1 brand for sensitive teeth¹.
It works by creating a barrier over sensitive areas or by soothing the nerves inside your tooth, offering 24/7 sensitivity protection when you brush with it twice a day, every day.
