Between the age of 9 and 12, more permanent teeth arrive than at any other age. During that time, your kids’ teeth are especially susceptible to sugar attack which can lead to cavities, so expert care for strong permanent teeth is important. Its ergonomic, size-appropriate handle makes the toothbrush easy to use. The flexible neck bends to help absorb excess pressure from brushing, while the ball-joint allows the brush head to adjust to the shape of the teeth, helping protect your kid’s gums from damage. A mixed bristle cut and head are designed to help clean developing teeth and interdental spaces. As your kid's mouth and teeth change, especially at this stage, the mixed length of the toothbrush bristles makes it easier to reach in-between teeth, thus improving their oral care. For optimal results, try using Aquafresh Advance toothbrush with Aquafresh Advance toothpaste. The toothpaste delivers fluoride into the enamel whilst having low abrasivity. It provides cavity prevention and enamel protection, helping keep your kid's teeth healthy, while staying gentle on teeth, cleaning in and spaces. As your kid grows more independent, they start to establish their own brushing routine. However, it is hard to get kids to brush for the full 2 minutes.
