Hi, so 36 hours ago, we realized my son (age 5, weight 43 lbs) had a fever of 102 (after playing fine all day) and had a swollen gum around one tooth.  The fever is still off and on, but now both his top and bottom gums are completely swollen.  He threw up once ~24 hours ago, but other than that does not complain of his stomach hurting.  Any idea what this is or should I take him in to see the doctor or dentist, or both?
Hello, Thanks for consulting Chat Doctor, Read your query, as your son has fever this swollen gums it can be secondary to viral fever it can be Viral dermatitis or swelling can be related to carious tooth, decayed tooth, root stump present, gingival enlargement due to gingival inflammation, periodontal problem may periodontitis also. I will suggest you to consult dentist for examination of swollen gum and rule out the cause of swelling, in meanwhile you can advise her to do warm saline gargle, you can apply ointment like gum paint on gums to reduce inflammation. Hope this will help you.
