Prolonged breastfeeding (after one year of age if it is daytime and / or after first milk tooth eruption if it is nocturnal) and its relationship with caries is a subject of great controversy.
There is no factor that causes cavities alone, however, most mothers who breastfeed on demand at night should know of the increased susceptibility to bacterial attack at night-time because saliva flow is almost nil, so by not cleaning the teeth after the intake, the risk increases.
Remember that breast milk does not cause cavities alone; But we see in the consultation many infants who present cavities at an early age when nocturnal breastfeeding is prolonged and combined with a lack of oral hygiene; When the baby sucks many times during the night; When the baby spends a lot of time with milk in the mouth; When complementary sugary foods exist; When there is insufficient fluoride exposure; When the child has enamel defects; When there is an early transmission of bacteria from the parents’ saliva; etc.
You need to start with oral hygiene as soon as you can, even if your baby does not have teeth. Take advantage of the bath time to clean the gums with a gauze, a damp cloth or a silicone thimble. Also, once the first milk tooth erupts, Decrease breastfeeding gradually during the night. If you decide not to, it is very important that you perform dental cleaning immediately after the intake. Don’t forget to take your baby to the pediatric dentist before his or her first birthday to know how to prevent the onset of cavities and other oral diseases.
