Curious as to what things a child might experience if they have a tooth infection?

Pain and fever : There could be pain with eating, or if a very hot or very cold liquid hits the area of the infected tooth. Also, there might be facial swelling. As with any infection, there could also be a fever. Be sure to have this evaluated by a dentist right away.

Pain/fever/swelling : A child with an infected tooth might experience some pain in the beginning of the infection, some fever when it gets stronger , and some swelling if the abscess did not break out from the gums, since baby teeth has very short roots.
