A study from the Faculty of Odontology at Malmö University in Sweden unveiled that the size of teeth in premature children is smaller than those of children who were full term. In recent years multiple studies of children's dental health have been published by researchers at the Faculty of Odontology in Malmö. The research involved 80 children born before week 33 of pregnancy."We have examined how their teeth are developing and, among other things, we've looked at their bites. We've also checked their need for orthodontic adjustments and found that it is greater than in the control group, children born at full term," she says.
