A member asked:

My son has a white spot under his tongue towards the back and he says it hurts sometimes and he had this for a few days now. what could it be?

A doctor has provided 1 answer

Canker sore: or aphthous ulcer is a small shallow sore or ulcer inside the mouth. They can be caused by mild injury but often there is no known cause, but often seem more common during viral infections. They usually heal in 7-10 days. If it enlarges significantly or lasts longer, please have it evaluated.
