A couple of days ago I had some dental work done. I recieved topical anesthesia, a couple pain killing shots, and laughing gas. The shots made my mouth very swollen, and the topical anethesia and the laughing gas made me unable to feel the entire left side of my mouth. While I was out of it, I chewed up that whole side, leaving large, raged canker sores.
After a couple days of pain which required me to take leftover Valiums from previous dental work, I tried drinking green tea, iced. It's cooling, soothing, and offers a great deal of relief.
For ALL of my adult life, I've been plagued by horrible outbreaks of canker sores, typically 2-3 very large sores at any given time. Six months ago I began drinking green tea daily as a substitute for soda. To my amazement, my canker sores disappeared and did not return. Green tea was the only dietary change I made (I still drink soda, just not as much). In addition, occasionally I will not have green tea for about a week, and soon enough the canker sores return.
I am not the type of person who really believes in folk or herbal remedies, but after discovering accidentally that green tea elminated my chronic canker sores, I am a believer in at least the health properties of green tea. I really cannot express what an improvement in quality of life this is for me and likely other chronic canker sore sufferers, so spread the word!
I noticed my relatively new habit of drinking green tea is drastically affecting the frequency at which canker sores appear in my mouth. They now seem to form only in the upper part of my mouth. Swishing tea on the sore greatly reduces the time it takes (24-36 hours) for it to heal. It's amazing to find this out after years of dealing with them.
