* Stop eating raw/whole flax seeds for now and avoid chewing on the affected side. * Rinse gently with warm saline: ½ teaspoon salt in a glass of warm water, 3–4 times/day, then spit it out. * For pain, a topical oral analgesic/anaesthetic gel such as benzydamine or an appropriate lidocaine preparation can provide temporary relief; follow the product instructions and avoid eating immediately after application.

* Eat soft, lukewarm/cool foods for a few days and chew on the opposite side. * Avoid spicy, acidic, very salty, hot, hard or crunchy foods until the wound settles. * Continue gentle oral hygiene with a soft-bristled toothbrush, but don’t aggressively brush directly over the wound. * Don’t repeatedly touch, scrape or check the sore with your tongue/finger. * Seek an in-person dental examination sooner if there is increasing swelling, pus, fever, significant bleeding, difficulty opening the mouth/swallowing, severe worsening pain, or a loose/damaged tooth. * If the lesion doesn’t show clear healing within 1–2 weeks or persists beyond 3 weeks, it should definitely be examined by a dentist/oral medicine specialist.

1) Visit the nearby dentist 2) Stop the habit of chewing raw flax seeds
