New York: Researchers from the Autonomous University of Tamaulipas are putting teeth into the discovery that nasal allergies, bottle-feeding, thumb-sucking and use of pacifiers by babies in their first year of birth, even if it is for 4 months, could throw teeth alignment in complete disarray.
Researchers are armed to the teeth with evidence gained from their study of 1,200 children between the ages of 4 and 5 who were sworn allies of their bottles, or pacifiers, or their very own thumb, of whom nearly two-thirds suffered problems in their dental arrangement. The findings of the study are published in the journal Archives of Disease in Childhood.
Researchers found that children who were bottle fed or used pacifiers or sucked their thumb much before they turned one, will have to contend with 'teething' problems, like the posterior cross bite. Nasal allergies also caused the children to breathe with their mouths open, leaving the tongue to pacify an itch, causing a flaw in what might have been a perfect alignment between the upper and lower jaw.
According to Dr. Francisco Vazquez-Nava, lead author of the study, when babies suck on bottles, pacifiers or their fingers, the muscles of the head and face do not move appropriately, as they do when they breast feed. This could impede the formation of the jaw and hard palate causing misalignment in the teeth.
