You will feel a twinge or short, sharp pain in your teeth when you eat or drink something piping hot or icy cold. Sometimes, it can be triggered even by by brushing of the teeth. This signifies that your teeth may be sensitive and require special attention. Teeth become sensitive when the inner layer of our teeth, called the dentine, is exposed. Providing all the advantages of a normal toothpaste while continually repairing and protecting your teeth against sensitivity, Sensodyne Repair & Protect truly brings hope to sensitive teeth sufferers.
