The dentine beneath teeth becomes visible as the gums recede or the tooth's enamel wears down. Tooth sensitivity is the term for the brief, acute pain that can occur when hot, cold, sweet, or sour food or liquids come into touch with exposed dentine. Sensodyne Fresh Mint toothpaste is a daily fluoride toothpaste that offers the advantages of a regular paste, such as strong teeth and healthy gums, while also helping to prevent tooth sensitivity. Additionally, it tastes minty, which leaves your tongue feeling clean and fresh. You can enjoy your favorite foods and beverages without worrying about sensitive teeth if you brush twice a day. Prior to use, always read the instructions and guidelines on the pack.
