The NUK® Design Shield Orthodontic Pacifier brings together function and design with an easy grab button. The contemporary shape and larger button bring the best designs to life. Sold as a 2 pack, these are button pacifiers with orthodontic silicone nipples. Over 55 years ago, NUK invented the orthodontic shape pacifier to mimic the natural shape of mom's nipple while breastfeeding. This natural movement inspired the orthodontic design of all NUK pacifiers so you can feel confident you are safeguarding your baby's oral development.
