The FDA recommends staying away from a lot of what’s currently on the market for teething babies. That includes jewelry, from anklets to necklaces to bracelets, regardless of whether the parent or child is supposed to wear it. Some of these are made from amber, which purportedly releases an anti-inflammatory called succinic acid. Unfortunately, not only is there no evidence that that happens, but it’s not even clear whether it would be safe for babies if it did. The FDA hasn’t evaluated these devices. But amber—like plastic, glass, or wooden beads—definitely poses a choking and strangulation hazard.
