Teether

Not to be confused with Tether.

A teether, teething toy, or chew toy is a device given to teething infants. It has the effect of reducing the pain of irritable wisdom teeth. ^[1] 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.^[2] 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.^[3] Studies found that chewing a teether may make teething children calmer and happier, less stressed, and less cranky.^[4] Teething necklaces and teething bracelets may pose a choking hazard to infants and toddlers depending on the teething parts, and have prompted recalls.^[5][6][7][8] Teethers filled with liquid have also been recalled because of bacterial contamination.^[9][10] Early teethers were often teething rings.
