<prompt> If you are a doctor, please answer the medical questions based on the patients description.My six year old daughterabout 38 lbs and 42 in, taking thyroid medication and has extremely low bone density with at least 3 compressed vertebrae has had a sore tongue and cheek for a week or two. It is on the right side and it hurts to touch or swallow. I can t see anything just looking as much as she will let me. There is no redness or swelling or lesions that I can see. There was some plaque and inflammation gums only, but I don t think that is what is causing the pain. It seems like it is getting worse and I m wondering if it is a blocked salivary duct and where would be the best place to take her dentist, pediatrician, or ENT.  <response>: Thanks for your query. I have gone through your queryThe soreness in the mouth can be because of the authors ulcers. The other possible cause can be because of the tooth infection. Nothing to be panic, consult a pediatric dental surgeon and get it evaluated. If it is an authors ulcer, you can take topical analgesic like choline salicylate. If it is a tooth infection, you need to take a course of antibiotics like amoxicillinif you are not allergic. Then the tooth has to be treated endodontically. I hope I have answered your query. Take care
