A: Teaching a toddler how to brush is helping create a lifetime of good oral health habits. So make tooth brushing consistent and fun. After breakfast and lunch, and before bed, get your toddler used to the idea of cleaning his teeth. You can use music, sing a silly song or give him a toothbrush decorated with pictures, or a character from a TV show or movie. Let your toddler see you brush, and let him try to imitate you. Congratulate him frequently on his success. Before you know it, he'll be asking you to brush!
