For immediate relief from severe gum pain, you can take over-the-counter pain relievers. Ibuprofen is highly effective because it reduces both pain and inflammation. Alternatively, acetaminophen can help manage the pain. Please follow the package instructions for correct dosages. Rinsing your mouth gently with warm salt water and applying a cold compress to your cheek can also provide temporary comfort. Since the pain is severe enough to keep you awake, it likely indicates an underlying issue, such as a localized infection, which requires professional treatment. Please schedule an appointment with a dentist as soon as possible for a proper diagnosis and long-term relief.

For temporary relief, you can take over-the-counter Acetaminophen (Paracetamol) 500mg to 1000mg every 4 to 6 hours (maximum 4000mg/day) or Ibuprofen 400mg with food. However, the combination of a high fever, severe headache, and back pain can be a sign of a serious underlying condition, such as meningitis, influenza, or a kidney infection. Because of this, you should not rely solely on self-medication. Please consult a doctor immediately for a proper diagnosis, especially if you experience neck stiffness, sensitivity to light, confusion, or nausea.
