Prevent Orthodontic Pacifier designed by a pediatric dentist has a patented Suction-Free Air Channel that helps reduce suction and palatal pressure. The soft suction-release bulb spreads wider as baby sucks for low pressure comfort. Prevent helps to lower the pressures that can create dental issues such as cross bites. The thin-stem design is minimally intrusive on baby’s mouth. Stage Two is for baby’s 6-12 months. Glow in the Dark.
