Long Lasting Benefits with Slow-release Fluoride Uniquely engineered to slowly release low level fluoride along with the optimal blend of calcium and phosphate mineral ions. This forms acid resistant fluorapatite, which is stronger than enamel and clinically proven to provide continuous, long lasting protection for up to 12 hours. Advanced Protection with Extra Fine Particles Designed to perform with excellence. Revolutionary bioactive material made with extra fine particles that bond to the tooth, penetrate and block any exposed pathways to the nerves, delivering superior protection against sensitivity while strengthening and protecting the tooth enamel. Clinically Proven with Smart pH Technology A toothpaste that knows what you need. Smart technology reacts to changes in oral pH triggered by sugary and acidic food and drink. It quickly releases mineral ions to neutralise acidity that could otherwise lead to decay and cause pain and sensitivity.
