The electric tooth brush 'Sonicare For Kids' distinguishes itself in terms of its special features for effective cleaning. The patented sonic technology ensures a dynamic flow of liquid that supports the cleaning performance of the bristles in the spaces between the teeth and along the gum line so as to dissolve plaque in locations that are difficult to reach. The KidTimer helps children to maintain the recommended 2-minute brushing period - the period is gradually increased over the course of 90 days. Two kid-friendly cleaning levels ensure gentle, age-appropriate cleaning: low level for kids from 4 to 6 years of age and high level for kids above the age of 7. Two different brush head sizes were specially conceived to ensure safe cleaning of teeth across various stages of development.
