Having a difficult time finding the right pacifier for your baby? NUK Orthodontic Pacifiers are accepted by 95% of babies* and feature a unique, improved asymmetrical nipple that naturally fits baby’s palate to allow more room for a natural sucking motion, reduces pressure on teeth and jaws, and helps prevent teeth misalignment. Invented over 60 years ago by pediatric dentists and doctors, the NUK orthodontic pacifier is modeled after the natural shape of mom’s nipple while breastfeeding. This makes for an easy transition from breast to pacifier and back. The heart-shaped shield fits perfectly under baby’s nose for easier breathing and prevents irritation. All pacifiers are BPA free and dishwasher safe (top rack only). (*Based on Market Research, 2017, tested with 307 pacifier users).
