In a new study by the University of Minho, Portugal, scientists investigated the effects of different teat shapes on the development of the teeth, jaw and palate.
In comparison: the original NUK shape and three teats with a different design.
In this computer simulation from the pacifier study, the child's sucking movements can be closely observed: the tongue presses the pacifier against the palate. The less stress this causes (shown here in red), the better.

The Study Proves:
The original NUK shape is best for teeth, jaw and palate.




NUK pacifiers have the lowest risk of teeth realignment and the lowest risk of deforming the palate.
