I suffered with canker sores as a child. Eating fruit or food that caused any trauma to the skin in my mouth guaranteed would result in a canker sore. Now as an adult, I only develope canker sores if I bite my cheek or lips.
I have tried everything. I would rinse my mouth out with salt water. I would put honey on it (which did help some). I even resorted to trying over the counter medications (not one to do medicine, but canker sores hurt, and I was looking for relief).
But what I found to work the best is oil pulling with coconut oil. My canker sore would stop hurting immediately after swirling coconut oil in my mouth for a couple minutes, and if I did it 3 or more times a day the canker sore would be gone in a day or two.
If you suffer from canker sores, and your healthcare provider agrees, try this and let me know if it worked for you.
Wishing you good health.
