Does anyone have any experience with Amber necklaces? Do they work?

Some parents say the beads work when body heat activates the amber to release succinic acid, which is believed to have pain-killing properties. But there is no scientific evidence to suggest the beads help, and the risks far outweigh any benefits. There is a strangulation risk. If your kids are pulling or trying to chew on them, they could break the beads off and choke. Health Canada also warns against using teething necklaces.
