I understand why salt is needed, to dry out the sore and heal it. My doctor said: “gargle with salt water that is as warm as you can handle without burning yourself?” Why was the “warm” aspect of this emphasized so much?

Pro-tip: use alum instead of salt (or instead of baking soda if that’s your usual go-to). It’s usually in the [spice or baking isle at most grocery chains in a small container](https://imgur.com/a/aYaFRuo).
I get canker sores because I bite my lip somewhat regularly and it always feels like salt and/or baking soda just prolongs the healing, to the point that it’s 1.5-2 weeks of pain. Hydrogen Peroxide doesn’t seem to expedite the healing either. Alum heals it in 2-3 days, sometimes even overnight if I get it on the sore quickly enough.
I just wet my finger so that the powder sticks to it, dab it on the sore, and let it sit until it no longer stings. Then rinse. I usually do it before going to bed and it drastically improves overnight. Wouldn’t recommend making a wash with it since it tastes kinda bad though.
