My cousin suffered from canker sours for YEARS!  She tried every thing that she could, finally the best thing to work is every night she used mouth wash with perioxide mixed in.  I think she used to mix it herself but then Crest came out with a Whitener Mouthwash that has perioxide alread in it.  Comes in a white bottle.

As for medication she used to buy this one medication, it was the only thing that worked but super expensive.  Hmmmm…. I can’t think of the name but if I come up with it I’ll let you know!!!

@ChocolateLime:  You poor thing!  I usually get a bad canker sore at the start of every semesters (fortunately never anything as bad as what you’re describing :-()  I stick to the salt water rinse as well.  The last time I had a bad one a few different people recommended I try milk of magnesia.  I couldn’t find the tablet they were describing so I didn’t try but I did just googled for you and apparently there’s a couple of options.  If you find the chewable tablets you can just hold the table on the canker sore for a while OR hold milk of magnesia in your mouth and let it bathe and coat the sores.  This is supposed to help with PH and make them better but also offer some pain relief.  

As far as food, when I had my wisdom teeth out and was in a lot of oral pain, I stuck with pudding, jello, and apple sauce.  I imagine those would all work for you because they’re soft and cool.  For something more substantial maybe some mashed potatoes?

With that many, it may be worth a trip to the doctor.  Good luck!

ETA: In case it wasn’t obvious, you spit the milk of magnesia out after.

@ChocolateLime:  I’m not sure how helpful this will be since yours are so bad, but instead of rinsing with salt water, I just stick salt straight on any I have and leave it there as long as I can.

I really hope you find some relief soon! 🙁 Good Luck!

A few years back I had an accident at work and a mucosal membrane irritant that I just happen to be allergic to got in my mouth. I think I had at least 9 large canker sores and they were painful enough to keep me from sleeping. My work comp doctor gave me 200ml of lidocaine gel which really helped with the pain. I think just about any doctor or dentist could hook you up.

In doing some research on my allergy I found out that almost all toothpastes contain the compound that got in my mouth. If your toothpaste has sodium lauryl sulfate in it I would stop using it until your mouth heals up. I use Burt’s Bees toothpaste which doesn’t have it. Since I changed toothpastes I have significantly fewer canker sores and I never get more than one at a time.

Rinse with vodka, sounds strange but it works for me. You can also try a baking soda rinse or peroxide rinse (be ubber careful not to swallow). Then apply any medication y’all have at the store for baby teething will help. Canker sours can be viral, so it may be worth a trip to the doctor.

aw cankers are the worse! I would stick to the salt water rinses. The simpler the better! I’d make sure you don’t have any vitamin deficiencies as well and maybe start taking a multivitamin if you don’t already. Hope you feel better soon!

@ChocolateLime:  yes anemia can definitley be a cause of canker sores. Definitely get that checked out. You may need an iron supplement on top of a multivitamin.

@LincsMama:  +1…. Just put salt on your finger and hold it on the sores till it goes numb… It hurts so bad but it will speed up the healing. 

Also, not sure if anyone else has said this but I would head to a doctor!! I get bad canker sores on my gums when I’m sick or stressed but I have never had my whole face swell up! Are you sure it’s not very infected?? You may need an antibiotic if it’s bad.

feel better!!!

I second what Eckle said I swapped from normal to SLS free toothpaste and saw a huge improvement (though SLS free is quite difficult to find, I had to buy it from a specialist store, then it was fluoride free so I ended up with a special fluoride mouthwash to go with it!). I tried Oraldyne for a while as that is supposed to help but it changed my taste completely so I had to give up. Currently I’m back on normal toothpaste and mouthwash and am going to try vitamin B12 as several people I know have sworn by that too. Good luck, I know how awful they can be.

I am prone to terrible canker sores whenever I bite my lip or cheek.  They get huge and throb and I wind up popping Advil like it’s candy.  It was always terrible and I put up with it for years.

Then someone suggested Lysine to me.  It’s a vitamin that you can buy in pill form.  If I bite my lip, I take one twice a day for a few days.  It prevents them from progressing to the torturously painful stage.  I don’t know if it will reduce the pain from the ones you already have but it is worth a shot.

I am not usually a big believer in vitamins or supplements, but this has made such a huge difference for me!

I hope you feel better soon.

I don’t have any great solutions, but just wanted to say I’m sorry you aren’t feeling well! I hate canker sores, I’ve had them pretty bad but never that bad. Hopefully some of the advice on here works, let us know what you tried!

I’ve tried lyseine supplements to no avail.


I also notice I get canker sores when I’m PMSing, is that real?
