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 three is for baby's 12 plus months.
