<s>[INST] Hi, may I answer your health queries right now ?  Please type your query here...My baby is 6 months old and cutting through her third tooth (first on the top gum) She has been upset all day and I've just noticed on her top gum, beside the new tooth, is an red open sore.  It's as though a tooth should be coming through but there isn't one there, it just looks red and sore.  When her other teeth came through they didn't look like that. [/INST] Hi.Welcome to HEALTHCARE MAGIC..I have gone through your query and can understand your concerns.....As per your complain it seems that the open sore area over the gum behind the newly erupted milk tooth can be most probably due to the other tooth that might be going to erupt in the due course of time and the gum might be tearing to let the tooth erupt..Do not worry, you can apply a numbing gel over the sore but be precise to apply a very small quantity that too only on the sore but only after clinically getting her evaluated by a Paediatric dentist..You can also do cool compresses over it..Feed with cool milk..Hope this information helps..Thanks and regards..Dr.Honey Nandwani Arora.. </s>
