Italian researchers have discovered there is a link between breastfeeding and straight teeth. The University of Milan findings show that both bottle fed infants and those who relied heavily on a pacifier were twice as likely to develop a crooked smile.
The findings were based on the detailed feeding histories and sucking patterns of a large sample of children (1099) between the ages of 3 and 5 years old. The children’s mouths were also examined by a dentist.
Over a third of the children had misalignments and poor spacing (altered occlusion). The front teeth of one in eight (13%) children didn’t touch, a condition known as anterior open bite. And 7% had “posterior cross bite” when the top back teeth bite inside the bottom back teeth.
