<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have had a severe toothache for three days now. I can barely open my mouth I have been vomiting since 4:30 this morning and have been running a fever . I have tried just about everything and nothing is helping. I do not have any insurance and cannot afford to go to the dentist what do I do? I cannot deal with this pain any longer I m losing my mind.  <response>: Hi, Thanks for asking the query, Severe tooth pain indicates that your tooth is infected , difficulty to open the mouth is due to pain and swelling . Stomach abscess occurs due to Chat Doctor. I would advise you to visit to the Dentist and get checkup done . Take an x-ray of the tooth. Take saline water gargles 3-4 times a day . Use chlorhexidine mouthwash gargles twice daily. Take tab amoxicillin 500 mg TDS , tab diploma TDS, Hope this helps out , Regards.
