Dr. Browns Teething Rings are specially designed by a pediatric dentist to relieve pain and provide comfort to babies during one of the most painful stages of infant development. Through chewing and anesthetic pressure, Dr. Browns Teething Rings help manage pain and promote proper jaw development. They are made from super-durable, bisphenol-a-free material and feature a specially textured surface that strengthens gums and chewing. They are ergonomically designed to be easy for babies to hold, reaching even the most difficult teething areas.
