I dipped a cotton swab into my bottle of tea tree oil and successfully treated two canker sores in my mouth. I held the swab against the sore while pressing a finger on the cheek/outer side and repeated three times within two days. I had an increase in saliva, which you need to be careful not to swallow. Just spit it out as necessary.

I applied the baking soda treatment on my canker sore and it works. I applied it directly on the canker sore, it stung a little, but thank God, the irritation and pain are gone.

My mom used to put glycerin on her finger tip then place it on the canker sore in my mouth, a few treatments later it was gone. Now I got my wife doing it as well. It is a important part of our medicine cabinet.

Sodium Bicarbonate (Baking Soda) has always worked for me. I get cankers on my tongue from time to time and I simply coat the canker with the Baking Soda and hold my mouth open for 30 seconds and rinse. By the next morning they are always gone.

At one time (very long ago), I used merthiolate, which was moderately effective on my canker sores. Now I use Fluocinonide which zaps the sores and keeps them from hurting while they heal quickly. It's a prescription drug, but inexpensive.

I am a 39-year-old female and have experienced canker sores since childhood. I have found that rinsing with hydrogen peroxide reduces the amount of canker sores I normally get, and when I have sores, it relieves the pain and inflammation associated with them. It also allows for less painful tooth brushing. Avoiding wheat also greatly reduces my canker sore incidence; something which I found out by chance.

I started my boyfriend on a daily dose of L-Lysine and it seems to help dramatically, along with taking an iron supplement every day.

The only thing that got rid of my canker sores, was being pregnant. I never had a single one the entire 9 months, and now that I've had the baby they have come back with full force. I'm not able to put anything on them because they are all in the back of my throat.

My Canker sores cleared up when I stopped using mouthwash. Using too much mouthwash too long and too often can kill all the "good" bacteria that helps keep the mouth healthy.

Using an antiseptic mouthrinse twice a day reduced the frequency and severity of my canker sores. Also, I just tried Debacterol last week and it seemed to help.
