Amber teething necklaces have seen an enormous rise in popularity over the last few years, but they don't come without risk, as one mother in America found out in the scariest way imaginable.
Mum-of-four Kasie, from Boston in the US, took to TikTok to share her scary brush with death.
When her 2-month-old baby was showing signs of teething pain she looked for something to help him. Having heard good things about amber teething necklaces, Kasie did her research and decided to purchase one.
The necklaces are made from fossilised tree resin and release succinic acid when it comes into contact with the gums. Although not scientifically proven, many believe that the succinic acid is a natural pain reliever, which is why it is considered suitable for teething.
Retailers and child safety experts alike warn that the necklaces should only be used when the child is closely supervised and never worn during sleep.
