Try doing salt water rinses. Dissolved 1 teaspoon of table salt in a cup of warm water. Hold the salt water solution in your mouth, gently swishing it around for a few minutes. Spit it out and then follow with clear water rinse. Do it a couple times a day it will aid the soreness and clear the canker sore.

Side effect of Methretrexate, which I've been taking for over twenty years. After you've cleaned your teeth put pure Aloe Vera jelly all over your gums and mouth including tongue. You must make sure its pure and has no other ingredients. It does the trick for me. It also stops the start of abcesses. 🤗

I experienced a sore on my lower lip linked to methyltrexate.

Annie my dentist told me if I got the sores to come on and she could help with it. I flare up with my gums swelling and bleeding. That's when we talked about it.i seems dentist regularly because of the flares. Hope this helps. Hugs for relief soon.
