My 6 year old son is complaining of a pain in his mouth and has been lethargic the past couple of days. We have taken him to the dentist but they were unable to determine what was wrong.  Is there something else I should be doing to determine what is wrong?
Hello, thank you for consulting with Chat Doctor. It looks that your son has rather some internal infection of jaw bone or there is some problem in his jaw joint. Better that you should visit a periodontist (child dentist) and get a full mouth x-ray done, as it will show the area of infection and even get a complete blood examination done. Hope it will help you.
