My 2 year old daughter got sick all of a sudden last Tuesday (December 13th) evening and threw up.  She went to the sitter Wednesday but she threw up again that morning.  She was a running a low grade fever off and on until Sunday (December 18th) so we were giving her ibuprophen.  Then Sunday night I noticed her gums were swollen and red and then they started bleeding.  I rinsed her mouth with warm salt water.  They are really sensative to where she can only eat soft food.  I have been putting baby oral gel on them also.  What do you think this can be?  Im taking her to her dentist today.
Thanks for your query, I have gone through your query. The bleeding gums could be because of the gum infection. Or it can be because of tooth infection like pulp polyp. It can be because of herpetic gingivostomatitis which is associated with fever and gum infection. Consult an oral physician and get it examined and take topical anesthetic and analgesics. Continue saline gargling. Get your children teeth cleaned once. I hope my answer will help you. Take care.
