The preventive pacifier was developed by a pediatric dentist to help minimize pressure inside the baby’s mouth. These pressures can sometimes create dental problems such as cross bites. Palatal pressure is reduced by creating an air channel that reduces suction and spreads when baby sucks. This patented suction free air channel opens when baby sucks for low pressure comfort. The pacifier Dr. Brown is part of a complete family of products that grow with your baby, including bottles and bottle accessories, pacifiers and teething, sports caps and solid feeding innovations.
