Sensodyne Deep Clean Toothpaste works inside the tooth to help calm the nerves for 24-hour sensitivity protection as well as gives advanced cleaning and lasting freshness through its foam boost technology. Sensodyne is specially formulated to relieve tooth sensitivity. When enamel is worn away or gums recede, the dentine underneath becomes exposed. This can lead to tooth sensitivity, for example, with hot and cold food and drinks. So what are you waiting for? Buy the product online at the best rate, right here!.
