* Purexa Sensitive Toothpaste is a herbal toothpaste that provides rapid and lasting relief from tooth sensitivity, a common problem that affects many people. * Tooth sensitivity occurs when the enamel, the protective layer of the teeth, is worn away or the gums recede, exposing the dentin, the inner layer of the teeth that contains nerve endings. * Purexa Sensitive Toothpaste contains natural ingredients that help to treat sensitivity by blocking the dentinal tubules, the tiny channels that connect the nerve endings to the surface of the teeth. * Some of the natural ingredients in Purexa Sensitive Toothpaste are spinach, rhubarb, arnica, and licorice, which have anti-inflammatory, analgesic, and soothing properties. * Purexa Sensitive Toothpaste also contains vajradanti, clove, and cinnamon, which are known for their antibacterial, antiseptic, and astringent effects, as well as their ability to strengthen the teeth and gums.
