24 May 2018 --- The US Food and Drug Administration (FDA) has warned that over-the-counter (OTC) teething products containing benzocaine may pose a serious risk to infants and children. The popular numbing agent can offer temporary relief to sore gums in teething infants; however, the FDA advises that companies stop marketing and selling these products for use. The agency is also raising awareness of the risks that, they state, come with other oral health benzocaine products.
