Avoid excessive exposure to fluoride, either in toothpaste or via bottled water. You should consult your dentist or pediatrician about the use of fluoride. Do not let your baby fall asleep or use the bottle in his mouth; this will minimize bacterial growth. Do not share your cutlery, straw or cup. Remember that your bacteria are transferable and may cause infection.
Putting all these practices in place, when to start care, and what specific steps to take or avoid, will ensure that your newborn has the safest and most effective oral care. For any parent, this is very peace of mind.
