3 month old teething

Hey guys looking for some advice.. My little man has been having a fever since Sunday last week I thought maybe its a cold or something since my husband works with kids and my oldest goes to school so he might have brung something home. I noticed my little man putting his hands in his mouth Alo and drooling. I took him Thursday to his pediatrician and they told me he was teething. I've gave him Tylenol the fever would go down and go right back up an hour later. Took him today to see the pediatrician and she just said the same thing teething just give him tylenol but it doesn't seem to comfort him any advice? thanks
