A Mother Asks the Nurse,"When Should I Begin to Clean

A mother asks the nurse,"When should I begin to clean my baby's teeth?" What is the best response for the nurse to make?

A) "You can begin when all her baby teeth are in."
B) "You can easily begin now. Just put some toothpaste on a gauze pad to clean the teeth."
C) "I don't think you have to worry about that until she can handle a toothbrush."
D) "You can begin as soon as your child has a tooth. The easiest way is to take cotton swabs or a face cloth and just wipe the teeth. Toothpaste is not necessary."
