When your baby starts teething someone is certain to suggest you buy an amber teething necklace, which is said to decrease teething-related discomfort.
Amber teething necklaces have become increasingly popular in recent years, so much so that even supermodel Gisele Bündchen got one for her daughter.
But do they really work? And are they safe for your baby to wear?
To find out, BuzzFeed Life spoke to Dr. Brent Bauer, director of the Mayo Clinic Complimentary and Integrative Medicine Program, who says "there is no plausible mechanism of action" when it comes to amber teething necklaces.
This — in plain English — means there is no realistic way the necklaces could create a biological process that leads to the reduction of teething symptoms.
But what about the succinic acid?
"There is no indication appreciable amounts could be absorbed transdermally," says Dr. Bauer. In other words, it is highly unlikely that simply wearing one of these necklaces against the skin can benefit your baby.
