The lesion is located exactly in the region where teeth meet .Even a small cusp, filling edge, or crowding can repeatedly traumatize the cheek. To resolve this you can
1.Avoid chewing on that side for a few days.
2.Smooth any sharp tooth edges (dentist can do minor enameloplasty)
3.Warm saline mouth rinses 2–3× daily
4.Avoid spicy/very hot food
5.Do not keep checking or biting
Next Steps
You have to see a dentist if it doesn’t heal in 10–14 days or if it increases in size or if it becomes hard, ulcerated, painful without biting
Health Tips
In most cases, once the biting cause is removed, the lesion resolves completely.
