Deleterious oral habits? That term summarizes all habits which are destructive for the teeth and supporting structures like lip/thumb sucking, lip/nail biting and buxism (teeth grinding). Based on previous studies, it its hypothesized that deleterious oral habits are connected to mouth breathing and the time interval a baby is breast fed: “Babies fed preferably with mother’s milk for a short interval or not breastfed at all have increased probability of developing mouth breathing and deleterious oral habits than babies breastfed for at least six months of age.” So does breast feeding prevent deleterious oral habits? In 2005, Trawitzki et al. published a study were they tested this hypothesis. They tested 62 children (3-6 years old) for their breathing and oral habits and sorted them in groups of mouth breathers and nose breathers. Statistic analysis of the feeding history of the study revealed that 100% of the nose breathing children were fed preferably with mother’s milk for intervals higher than three months. However, there were also breast fed children among the mouth breathers (37.5%). Moreover, the study showed that the feeding history of the children showed no significant difference in feeding by milk bottles between mouth and nose breathing children. Significant differences occurred in the presence of deleterious oral habits between mouth and nose breathers. Suction and biting habits were more common in mouth breathers compared to nose breathers. But what do we learn from these results? Does breast feeding prevent deleterious oral habits? No.
