This child's dental office was opened exclusively to help little girls make their teeth white again. Have the little girl open her mouth and check to see if her teeth are clean. Spray some water into the child's mouth, grab the toothbrush nearby, squirt some toothpaste onto the toothbrush and start the brushing process. Once the girl's teeth have been thoroughly brushed, spray water to rinse the teeth and ask the girl to spit out the water. Take up the dental floss and use it to do another round of cleaning just to be on the safe side.
