Stay away from necklaces and bracelets used to relieve teething pain in infants, the US health regulator warned parents and caregivers on Thursday, after reports of a death and several serious injuries. Known as 'teething jewelry', these products come in various shapes and are used by parents and caregivers to relieve infants' teething pain and other ailments. They are also often used by children with special needs such as autism or attention-deficit/hyperactivity disorder (ADHD) for sensory stimulation.The FDA said it received a report of an 18-month-old, who was strangled to death by his teething necklace during a nap. Some parents have chosen to give their children a bead necklace to chew on, which may seem convenient since it is always on their bodies. Parents that want to keep things 'natural' sometimes give their infants amber necklaces, as the resin form them is advertised to have soothing anti-inflammatory properties. But if you're considering doing the same - don't, the FDA urges. The agency also received reports of injuries including that of a seven-month-old child who choked on the beads of a wooden teething bracelet and was taken to the hospital.
