Here's a general guideline I found. Some get teeth earlier than others, obviously. The molars are the ones that generally take the longest and make the babies the most miserable because they cause more soreness. They form a blister under the gums as they're coming up before they break through the gum surface, and babies often run some fever with that. Teething increases the amount of drool they produce, too!
