For babies: Massage the gums with an infant finger brush or washcloth just prior to the eruption of the first primary tooth. This will prepare your baby for daily dental care and may help alleviate teething discomfort.
When the first tooth erupts: Use a soft-bristled toothbrush in a circular motion on all surfaces, especially along the gumline. This will remove plaque bacteria that can lead to decay. Any soft-bristled toothbrush with a small head, preferably one designed specifically for infants, should be used twice daily: in the morning and before bedtime. Remember that most small children do not have the dexterity to brush their teeth effectively on their own.
