Ours is a culture that prioritizes instant gratification, and is instinctually reflexive about taking a pill or other fix immediately to end pain. When, actually, it is pain that can in a number of conditions be our greatest gift.
Society often pathologizes normal development. When this is done, a medicine must be made for treatment (needed or not). The FDA recently called out a group of over-the-counter drugs for being harmful and without benefit for infant teething.
In 2012 the FDA warned parents against using products containing the local anesthetic benzocaine to relieve their infants teething pain. Today the agency extended that advisory to viscous lidocaine another local anesthetic.
