Hydrogen Peroxide

Take an ice cube with frost still on it over the canker sore and it will rip off the white part, and numb it at the same time. Then take hydrogen peroxide and hold it on the sore mixed with Apple Cider vinegar for up a minute or two. This will sting like a bitch. After all this take a Q tip and activated charcoal and scrape the crater from the former sore. Then take just the charcoal and make a paste and leave it for a few minutes. Problem solved overnight or at least smaller. Or alternatively you could use alum which also burns like hell.

I discovered to use on canker sores Hydrogen Peroxide on my own a few years back. I used it 30 sec per day, everyday, and now I have had one, maybe two canker sores since then. I think the Hydrogen Peroxide interrupts the life cycle of the virus by destroying the infected cells. That was back in 2001!

I have always used hydrogen peroxide for skin infections, insect bites, cankers, cold sores & deleting blood stains. Results are quick & inexpensive. I dab it on my finger, straight from the bottle, to apply to a cold sore or canker. I have never had a cold sore for more than a day. When I was a teenager, I also applied some to any pimples that might crop up.

Take one capful of H202 and hold in your mouth for 10 minutes daily, then spit it out. No more canker sores and your teeth will be whiter without expensive pastes.

Hydrogen Peroxide def works for canker sores...my doctor prescribed some mouthwash that just numbed it for a few hours..but peroxide reduces the pain and it also helps cure canker sores

For canker sores, either dab hydrogen peroxide directly on the canker sore until it stops bubbling, or hold and swish 2-3 tbs hydrogen peroxide in your mouth for 30-60 seconds. Spit out and repeat 2-3 times. DO NOT SWALLOW. Rinse your mouth well with water after using the peroxide in either method. The canker sore/s will be noticeably improved and much less painful within 24 hours. They should disappear altogether within 48-72 hours.
