New adult teeth are not as strong as you might think. Enamel on new adult teeth is softer and more vulnerable to decay due to sugar acids, the key cause of cavities. Also the mix of little and big teeth makes them more difficult to clean.
Aquafresh Big Teeth Mouthwash is designed for 6 years with a mild taste flavour and an antibacterial, sugar & alcohol free formula with fluoride for strong teeth.
Preparation and Usage: Always follow the label directions: Use twice daily. Measure 10 ml and rinse for 1 minute then spit out.
