[/INST] Hi Dear, Welcome to Chat Doctor. Understanding your concern. As per your query your son have symptoms of headache and toothache which is due to radiating pain from an infected tooth that can cause pain in side of head due to bacteremia and septicemia. It could be due to injury to head leading to residual headaches. Need not worry. I would suggest you to consult a dentist and get evaluated and get X-ray of concerned tooth done and start treatment either root canal treatment or extraction depending upon condition of tooth. If this is not the cause get your blood pressure monitored and start treatment accordingly. Maintain oral hygiene by brushing and flossing. Dentist may refer you to neurologist if it is related to head injury. Hope your concern has been resolved. Get Well Soon. Best Wishes, </s>
