Peroxide on a q-tip will help them to heal way faster and doesn't have the crazy stinging like most solutions do.

Peroxide is generally bad for open wounds as it destroys the cells around the wound. Edit: wrong , comment below and above correct

Many treatments for canker sores (aphthous ulcers) cause a superficial zone of necrosis. If you think peroxide is harsh, check out debacterol. These treatments typically decrease the duration of discomfort and reduce the time required for the mucosa to heal.

Interesting, I looked up treatments and why they worked just now and found out the goal of them for cankersores is to debride the ulcer , which makes sense.

Can you please tell me what percentage peroxide you use?

I use 3%. And when I have a really bad one, I don't even bother with the q-tip I just straight swish the peroxide in my mouth like mouthwash being careful not to swallow any, then spit and rinse like crazy. It really helps cut down the time of the painful period of the canker sore.

Good to know! There is prescription here in Canada that's called oralcort, is a steroid the helps alot to me. However if this works, then I don't need to get the prescription. Thanks

Best of luck! Hopefully it works as well for you as it does me. One caveat I noticed is that the sooner you treat it the faster it heals. So I usually rinse as soon as I notice a canker sore when it's fresh and small.
