what are canker sores and why are they so darn painful?

I am currently reeling from one, and I don’t understand where this little white dot came from and why it can cause so much pain.

Can’t answer to your question, but I thought I’d let you know that eating a handful of walnuts will cause canker sores for some persons. Apparently it’s the little skin on the walnuts that can do it.

Avoid Sodium lauryl sulfate (SLS) in toothpaste. That’s the #1 cause. It changed my life. SLS is completely useless and should be illegal in toothpaste IMO. It’s just here to generate foam and makes it look like the toothpaste is working. Kids toothpaste often don’t have SLS.

Certain foods can be triggering. For me it’s walnuts and especially canned food.

In my experience using a mouthwash like listerine remarkably accelerates the recovery. **You have to gargle really aggressively for 60 seconds, and regularly mix fresh air in your mouth. The stronger you feel that mouthwash burn the better.**

I only use mouthwash when I have a sore, and generally they are gone after 48h with mouthwash. Otherwise they can last a week.

I had canker sores constantly as a child, it really sucked.

Orajel works well, and also simply swishing with salt water can give you some relief. I was always told it was a result of indigestion.

I used to get them chronically. I asked my dental hygienist about it and she suggested taking a multivitamin with chromium. It worked, and now I only have a few a year. Nutrient deficiency is one possible explanation, but people seem to get them for other reasons too.

There is a product called Oral Medic. Use that to treat them. And as others have said, use the right type of toothpaste: Sensodyne.

I have a process to get rid of canker sores and it works folks.

Take your toothbrush and scrub it. That’s it. It will be incredibly painful, but it will cause blood to clot and repair the sore much faster than it would heal on its own.

Mine seem to clear up in a day at two.

As far as what they are, I can’t add anything other commenters haven’t already mentioned.

One treatment that helps me a lot is to begin applying Abreva (docosanol) as soon as I notice a sore is forming. It’s technically a cold sore medication, and as others have mentioned cold sores and canker sores are different. I’m not sure why it works, but for me it really does. It reduces both the intensity and duration of my canker sores. Only downside is that Abreva is expensive. But the generic pharmacy brands work just as well and will save you a bit.
