Greetings from Healthcare magic members, I can understand your concern regarding toothache. Most of the time toothache occur from inflammation of pulp tissue called pulpitis (which is central part of tooth containing blood vessels and nerves). This is primarily caused by tooth decay, trauma and infection. There could be other reasons of pain as well which include gum disease, cracked teeth, poorly placed fillings or crowns, failing or leaking restorations etc. So, proper treatment has to be undertaken after detailed clinical and radiographic examination of the affected tooth or teeth. For temporary relief, over-the-counter pain medications such as acetaminophen (Tylenol), ibuprofen (Advil) or Diclofenac potassium (Rapidus) may be used. Also, avoid hot or cold foods and chewing from the affected side because this may make the pain worse. Hope this answer is helpful. If you have any further followup questions, please do not hesitate to ask. Regards, Dr. Khoja
