Say hello to Smile Street. My Dental Buddy now has a whole new world to explore. Your child meets Tito and friends and unlocks a little more with every brush. New: guided two-minute brushing for morning and night, a new word to learn each time, rewards and a trophy room, and a calmer night-time mode for bedtime. Same two good minutes, a lot more to love. Built by NHS dentists, for ages 3 to 6.
