For temporary relief from jaw and tooth pain, you can take over-the-counter pain relievers like Ibuprofen (200?400 mg) or Acetaminophen (500 mg), provided you have no contraindications. Warm saltwater rinses can also help soothe the area. However, left-sided jaw pain can sometimes be a warning sign of a heart issue. If your jaw pain is accompanied by chest discomfort, shortness of breath, sweating, or dizziness, please seek emergency medical care immediately. If there are no cardiac symptoms, please see a dentist promptly, as pain medications only temporarily mask underlying dental infections, cavities, or TMJ disorders that require professional treatment.
