<s>[INST] My 6-year-old son has been complaining of pain on the roof of his mouth for about 3 days now. Today seems to be much worse for him....says it hurts to talk, eat, etc. He also is running a low-grade fever today (100.3 F). Just wondering what it could possibly be and if he needs to see the family doctor or his dentist. Thank you in advance for any advice you may have. [/INST] Thank you for the query.The description indicates that he needs to be taken to family doctor first so that he can decide if the problem is teeth or some other one. If its not a dental problem he can suggest treatment or he can guide you to a dentist if needed. </s>
