Thanks for the question. Your concern is appropriate for the condition, as this is very painful for the child. Teeth while erupting push gums from inside, teeth are very sharp,(you must have noticed) which causes swelling of gums. Some times gums are normal because teeth are not pushing from inside at that time. You can give him something to chew on, like carrot, making sure things are clean and he doesn t take a big bite. You can take him to a pediatrician who can prescribe some anti inflammatory for such times. It will help the child and relieve him of severe pain.
