I have 5 killer canker sores in my mouth. 3 on my gums and 2 on my tongue. It’s been 4 days since they flared up and I’ve never had such a bad experience with them before, even during the 2 years I had braces. I’ve been using “Kanka” which helps numb the area, but I can only use it 4 times a day. I know about gargling salt water/using hydrogen peroxide, but does anyone know of any other home remedies to help with the pain?

(The tongue ones are the absolute worst so if anyone can help me with those I will probably cry tears of joy)
