You probably won’t care about this unless you’re raising children. If you are, you know that there is a raging folklore-and-urban-myth debate about how much crankiness can be attributed to teething. “(M)any …symptoms commonly associated with teething — such as high fevers, diarrhea or

vomiting — cannot be blamed on the imminent emergence of a new tooth, according to results of one of

the largest studies of its kind…Furthermore, there was no cluster of signs that could help parents predict when a

tooth was about to emerge. No particular symptom — such as biting, drooling or

gum rubbing — was seen in more than 35% of infants during the teething time.”
