When an infant seems really uncomfortable when teething, what should and what shouldn't you give them?

A) You should give them teething rings, cold washcloths, or a clean finger to chew on, and avoid giving them aspirin or topical medications containing benzocaine.
B) You should give them over-the-counter pain relievers or alcohol-based teething gels, and avoid giving them anything cold to chew on.
C) You should give them small toys to play with, and avoid giving them any medications or teething-specific products.
D) You should give them sugar-free gum to chew on, and avoid giving them any oral hygiene products containing fluoride.
