Primary incisor teeth may be spaced farenough apart that they do not require flossing. When adjacentteeth are touching, dental floss should be used to clean interproximal(in between) surfaces of teeth. Gentle pressure should be usedduring flossing to prevent injury to the gingival tissues as floss isguided between the teeth. Again, coaching, assistance, and completionof the task by the caretaker will be necessary. A flossing aidmay provide the caregiver easier access to the posterior teeth.Flossing is important to prevent interproximal caries and gingivitis.
