I understand you are experiencing discomfort. For temporary relief from the pain, you can take over-the-counter pain relievers like ibuprofen or paracetamol, following the package instructions. To help soothe and clean the wound, gently rinse your mouth with warm salt water a few times a day. Please avoid placing any pain relief tablets directly against the gums, as this can cause irritation. While these steps will help manage your symptoms temporarily, it is very important to see a dentist. Molar pain with an open wound needs a proper physical examination to treat the underlying cause, such as an infection or decay, and ensure it heals safely.
