How do you treat a swollen frenum?

To treat a swollen frenum, maintain good oral hygiene by gently brushing the area with a soft toothbrush and using an antimicrobial mouthwash. Apply a cold compress to reduce swelling and discomfort. Over-the-counter pain relievers like ibuprofen can help alleviate pain. If swelling persists or worsens, consult a dentist for further evaluation and treatment.
