When the protective layer of teeth (enamel) is worn away or gums recede, the dentine underneath can become exposed. When the exposed dentine comes in contact with hot, cold, sweet, sour food and drinks or even toothbrush, it can trigger a sharp short sensation called tooth sensitivity. Sensodyne has designed and formulated an entire range of oral care products (toothpaste, brushes and mouthwash) to help protect people against tooth sensitivity while still providing the benefits of fluoride, cavity protection and fresh breath. Normal eating or drinking exposes teeth to sugars or acids, leaving them vulnerable to wear & tear, specially at night. Sensodyne Complete Protection+ Mouthwash is an effective way to complete your oral health routine. It helps protect against tooth sensitivity as well as provides multiple oral care benefits like lasting freshness, cavity protection and strong enamel. The formulation is uniquely designed without alcohol for apleasant usage experience without burning sensation in mouth. Cool Mint flavor gives lasting freshness while fluoride protects against tooth wear and cavities. Twice daily usage after brushing helps protects from sensitivity to help you enjoy your favorite foods and drinks without the worry of sensitive teeth. Sensodyne Complete Protection+ mouth wash is available in two pack sizes - 250 ml and 100 ml. For optimal care, use together with a Sensodyne paste & toothbrush. Always follow instructions and guidance included on the pack before use. Sensitive teeth may indicate an underlying problem which needs prompt care by a dentist. If symptoms persist or worsens, consult your dentist.
