Diaherra while teething... the myth? Or a fact?

Baby teething time is an excited yet torturing moment for parents. The teething sign is the one that give us the headache, heartache, and sleepless nite! Maximus is showing the bad sign of teething for the upper teeth... purging, cranky, feverish, and lacking of sleep due to stomach discomfort.
Thanks to richrach (http://richrach.blogspot.com/2009/03/sarahs-teething-again.html) that I have learn that it's a norm for baby to purge while they are teething. But Maximus has too much of purging and so being afraid of dehydrated we went to the doctor again... We got oral hydration salt and other medication to stop the diarrhea. And we found out from doctor that purging is not the sign for teething... baby purge is because of biting or putting things into the mouth during the teething period. So bacteria and germs infected the tummy which cause intestine to be infected. Therefore diarrhea. This happened mostly during teething period because of the itchy gum, baby tends to bite anything and everything that they can grab...
So we have to be more aware that while teething period, baby do not bite or put everything into the mouth. I debated with my hubby about it although he argued that when Maximus got his bottom teeth he didn't have diarrhea at all. Well, the fact was during that time Maximus wasn't able to crawl yet ... not mobile so less chances to grab things easily to put into his mouth unless we gave it to him.
To debate also with richrach's blog, diarrhea is not the cause of teething! That's why we didn't read anything about having diarrhea while teething. So the hypothesis is not true... "Diarrhea is caused by teething." The culprit is that the germs that go into the tummy because of gum itchiness and baby biting things to sooth the itchiness.
There are lots to debate about it anyway... but it's what according to the doctor. Therefore, I can conclude that having diarrhea is not a sign of teething. Anyone want to second this?
