If you have sensitive teeth, it's probably due to exposed dentine. This is the softer substance beneath your tooth enamel. It is full of tiny holes that lead directly to the nerve at the centre of the tooth, which is what causes sensitivity with mainly cold but sometimes hot food and drinks.
With Sensodyne Gentle Whitening you'll get dual benefits: a toothpaste that provides long lasting care for sensitive teeth**, while also helping to whiten your teeth by removing stains**.
