A teether, teething toy, or chew toy is a device given to teething infants. Most modern teethers are silicone, but can also be made of wood or rubber. Some teethers are filled with a fluid or gel that can be frozen or refrigerated. They differ from pacifiers in that they are intended to be chewed, rather than sucked on. They come in a variety of different shapes. Teethers may help relieve teething pain and help new teeth penetrate the gum, as well as provide a form of entertainment. Teething necklaces and teething bracelets may pose a choking hazard to infants and toddlers depending on the teething parts, and have prompted recalls. Early teethers were often teething rings.
