This pain and swelling at the back of your mouth is very common and often due to an emerging wisdom tooth or localized gum irritation. For temporary relief, you can apply a topical anesthetic gel containing lidocaine or benzocaine directly to the sore gum. Over-the-counter anti-inflammatory medications like ibuprofen, or pain relievers like paracetamol, can help ease the pain and reduce swelling. Gently rinsing your mouth with warm salt water or an antiseptic mouthwash containing chlorhexidine three times a day will also help keep the area clean. Please schedule a visit with a dentist for a proper evaluation and targeted treatment.
