[|Human|] My son developed a swollen upper lip last night, and it was gone again this morning however he had a lot of pain in it and was verydistressed he has been complainig of a sore mouth for a few weeks now and we are wondering is it hi teeth which are very small or would it be a gum problem he has
[|AI|]  Thanks for your query, I have gone through your query. The swelling over the lips could be because of the allergic reaction, or it can be extension of the tooth or gum infection. Consult an oral physician to rule out these conditions. If it is tooth or gum infection you need to take a course of antibiotics and treat the causative tooth. If it is an allergic reaction, then it has to be treated with anti-allergic agents like cetirizine. I hope my answer will help you, take care.
