Once teeth erupt, plaque begins to form. Because of the toddler’s limited dexterity, the parent needs to perform toothbrushing. The caregiver can access a young child’s mouth by having the child lie on a bed or by cradling the child’s head in the caregiver’s arms (Figure 2). Toothbrushes with soft bristles and a small head are recommended for infants and toddlers. If toothpaste is used, only a pea size amount is needed. Flossing is not necessary until interdental contacts become present. Developing a daily routine in the child’s plaque removal is crucial to the establishment of a regular tooth- brushing habit.
