Hi!
No need to worry until it pains or there is some kind of irritation in nearby tissue.
If problem persists, Iwould suggest you to contact me as I have treated such cases successfully in the past.
Next Steps
Warm saline rinses. (3 times a day)
Betadine mouthwash (Daily once before you sleep)
Health Tips
Do not over irritate or touch it many times. Avoid very hot or spicy food for a week. This should subside on it own.
