• All NUK soothers are approved by the British oral health foundation for promoting healthy oral development. • Orthodontic shape which mimics a mother\'s nipple during breastfeeding for a more natural soothing experience. • Flat shape helps prevent pressure marks and stops the soother from falling out of baby\'s mouth. NUK soothers have a specially designed orthodontic shape that adapts to baby’s mouth. This helps to exercise the lips, tongue and facial muscles, which promotes the healthy development of teeth and jaw. The flat shape of the Disney soothers helps prevent pressure marks and also stops the soother from falling out of baby’s mouth. The NUK air system helps to ensure the mouthpiece remains soft and flexible. A handy reusable storage case can be used to keep the soothers safe and clean but also to hygienically clean the soothers with steam in the microwave.
