Dr. Browns™ Prevent Pacifiers are another patented innovation of the company, aimed at protecting and promoting the proper development of babies. They are specially designed by a pediatric dentist to reduce pressure inside the babys oral cavity, eliminating the risk of dental problems. They have a special air escape passage that reduces palatal pressure (i.e. the pressure on the babys palate), reduces suction and disperses air with sucking. Thus, the use of the pacifier is done without the baby feeling pressure, relaxing him. Dr. Browns™ Orthodontic Pacifiers are available in a wide variety of colors and designs, in a pack of 2.
