The NUK Genius Soother has been developed in partnership with dental experts worldwide, & is the new generation of NUK Soother. Still based on the approved orthodontic NUK shape, but enhanced with a softer & more flexible baglet, to further reduce the pressure on babys jaw & teeth, as well as the risk of teeth misalignment.A handy soother bag keeps the soother clean & safe when at home or whilst out & about. The NUK Air System helps to ensure the mouthpiece remains soft & flexible, encouraging the correct development of your childs teeth. Integrated grooves enable saliva to flow away from the babys mouth preventing skin irritations. NUK Teats & Soothers are approved by the British Dental Health Foundation.
