Teething is something that can seem to go on and on for months before there's even any sign of an actual tooth.
I found the following to be helpful:
Teething begins around 3-7 months and lasts until approximately 2 years of age, when all 20 baby teeth are present.
Generally, the first tooth to erupt comes in at 6 months. This tooth is the bottom front incisor.
When a child is teething they tend to be irritable, drool, chew on everything and the gums may be red.
Fever and diarrhea are not related to teething.
Ease discomfort with a teething ring, clean damp washcloth or by rubbing gums with your finger or the back of a cold spoon.
Do not use teething cookies/biscuits because of the sugar content that can lead to tooth decay.
Use medications/ointments only on the advice of a dentist.
Remember to clean baby teeth as soon as they come in.
