Mouth cleaning, in addition to daily brushing and flossing, can increase the cleanliness of your mouth. Antibacterial mouthwash reduces bacterial and plaque activity, leading to gingivitis and gum disease. Fluoride mouthwash also helps to reduce and prevent tooth decay. Always talk to your dentist about new products that you are interested in trying. Not everyone should use fluoride mouthwash. For example, fluoride cleaning fluids are not recommended for children under 6 years of age as they may swallow them. Always check the manufacturer's labels, precautions and age recommendations, and talk to your dentist about fluoride mouthwash.
