The Tie-Dye Orthodontic Pacifier not only looks great, but helps promote healthy oral development for your baby. It gently exercises your baby's tongue, palate and jaw and promotes proper teeth alignment by helping your baby avoid thumbsucking. The grooves in the pacifier shield allow air to circulate, preventing skin irritation. All NUK® orthodontic pacifiers help to soothe and comfort your baby so you can sleep. And, the colorful tie-dye designs coordinate with matching NUK® orthodontic bottles and NUK® Learner Cups.
