We have developed two lines of Dr. Brown's pacifiers to provide a choice for every mom. Our Perform™ pacifiers have an orthodontic shape and ultra-thin stem that's easy on baby's mouth and teeth. Our new PreVent™ pacifiers are a patented design, years in development by a pediatric dentist, that feature an air channel in the bulb that helps reduce suction and the pressures on baby's mouth – which can create dental issues such as cross bites.
