Does anyone know how to get rid of a tongue ulcer...?

Does anyone know how to get rid of canker sores as the title suggests...?

Recently, I was so tired that I developed a mouth ulcer.

The problem is, I have severe canker sores, so I'm afraid to eat anythingㅠㅠ

You just need to take a simple rest to recover your immunity.

It's really difficult because I can't take a break right now...

Is there a simplest way to get rid of a tongue ulcer?

I don't think it's right to say to apply Albolchil... lol

They say to try hard to pack a mouthwash with antibacterial effects.

Does the method to get rid of canker sores really work?

How do you handle it when you get a mouth ulcer?

I really want to get rid of this mouth ulcer quicklyㅠㅠ
