Pepsodent Sensitive Expert Professional isn't your average toothpaste. It boasts a unique formula with a two-pronged approach to tackling tooth sensitivity. Firstly, it contains potassium nitrate, a well-researched ingredient clinically proven to desensitize nerve endings in the teeth, effectively reducing the sharp pains associated with sensitivity. Secondly, the formula incorporates a special technology that forms a protective layer over exposed dentin, the underlying layer of the tooth that contributes to sensitivity. This double action ensures comprehensive relief, allowing you to enjoy your favourite foods and beverages without worrying about discomfort.
