The prevent pacifier has been developed by a paediatric dentist helps minimize the pressures inside baby's mouth. These pressures can sometimes create dental issues such as cross bites. Palatable pressure is lessened by creating an air channel that reduces suction and spreads apart when baby is sucking. This patented suction-free air channel opens up as baby sucks for low pressure comfort. Dr. Brown's prevent pacifier is part of a complete family of products that grows with your baby, including bottles and bottle accessories, pacifiers and tethers, trainer cups and solid feeding innovations.
