Brushing alone is not sufficient to remove all plaque and bacteria in the mouth. An antibacterial mouthwash helps to control bacteria growth in the places that are difficult to reach with tooth-brushing alone. Sunstar GUM Mouthwash contains Cetylpyridinium Chloride (CPC) that helps to reduce bacteria causing cavities, plaque and bad breath, thus promoting healthier teeth and gums. It is useful for children who are susceptible to cavities.
