I have mild toothache and earache. I brush my teeth and rinse my mouth daily, yet I’m unsure why I’ve developed this condition. Could you please explain what might be causing both toothache and earache?

Toothache accompanied by ear pain may be caused by conditions such as dental nerve inflammation. If dental nerve inflammation is not promptly and effectively treated, it may lead to referred pain, thereby triggering both toothache and ear pain. Treatment typically involves the appropriate use of anti-inflammatory medications under a physician’s guidance—for example, artificial bezoar and metronidazole capsules. Additionally, avoid excessive stress in daily life.
