Tea Bags

[YEA]  Has anyone ever heard of using tea leaves to resolve a canker sore? I have tried it in the past and it has worked and I was wondering if anyone else had used this technique.

[YEA]  My husband told me to put a tea bag on my canker sore. It definitely took away the pain! As for curing it, I think it speeded up the process. The tea bag remedy is good for any type of mouth sores because of the pain relieving effect. I usually use black tea, simply because that's what I have around most of the time. Green tea also works, and I'm sure any kind will probably do the trick. It is not necessary to steep the tea first, however it does work better if the bag is already wet before applying. If the strong taste is too much for you, drinking brewed tea also works if you swish it around over the canker sore while you drink it. However, it's been my experience that the tea bag directly on the sore is much more effective.

[YEA]  First, the tea bag, was very helpful in the healing process it definitely made the pain disappear in minutes as for the peroxide,i would use this as a last resort, but it does work! The tea bag was very successful! try it! it most definitely works! Use the peroxide as a last resort!

[BETTER BUT NOT CURED]  Yay - My second painful canker sore just showed up yesterday, and last night it woke me up from my sleep. I tried dobbing some tea tree oil on it with a q-tip, and the pain was immediately eased enough to get back to sleep. I don't know if it will help speed the healing, but it does certainly help a great deal with the pain!

[YEA]  Stop a herpes outbreak: THC, the active ingredient in marijuana kills the herpes virus. It stops the pain of a canker sore on contact. You do not need to smoke or get high at all, just put a pinch into rubbing alcohol and apply with a q-tip.

[YEA]  I have suffered all my life with constant canker sores in my mouth. I have found a prevention. I have tried everything - all the over the counter treatments - canker sore toothpaste - canker sore mouthwash - paste - patches - perscription meds - ALL OF IT and none really worked untill I stumbled on a real answer. THE REAL ANSWER is to use _____ MINT TOOTHPASTE for sensitive teeth. I found this totally by accident. After 55 years I found it by asking my dentist about a tooth that was sensitive to cold and he advised that I use ____ toothpaste. I did and since I had always had canker sores I noticed within a week that they were all gone. I haven't had a canker sore in over a year now. I do all the bad things you can't do with canker sores now. I enjoy soft drinks, eat citrus fruit, chew gum, eat walnuts, eat pinapple. I contacted the makers of _____ and they aren't interested in promoting their product for this application - I was so mad. No wonder people suffer with different things - no one is really interested in a cure. I have promoted this idea to all my family and friends and all have the same success. PLEASE - PLEASE - PLEASE pass this on. From someone that suffered all my life - this really changed my life.

[YEA]  Placing a dab of toothpaste on a canker sore inside the mouth will reduce the pain and heal the sore quicker. This is a remedy my mother has known since she was a child in Belgium.

Toothpaste Without Sls

[YEA]  SLS-free toothpaste eliminated my canker sores. I was getting numerous canker sores each month, sometimes several at a time.

I tried canker sore gels. They eliminate the pain temporarily but not the sore itself.
I tried baking soda. That seemed to help shorten the duration a bit was very painful for about 5 minutes. Similarly, apple cider vinegar was painful and seemed to cause a slight improvement in symptoms but didn't eliminate the sores.

I tried a pinch of alum, which also stung to apply and really pickled my lips. I coudln't determine whether that helped much either.

Finally, I bought SLS-free toothpaste 6 months ago. I haven't had a full-blown canker sore since! I think 1 or 2 may have thought about starting during that time, but each time they went away without forming or causing pain.

Definitely! I regularly got canker sores and even once had a large lesion on the inside of my cheek and swollen lymph glands (I had the habit of holding my toothbrush in my mouth while I attended to something else before I finished brushing). I used baking soda to brush with for awhile and that was fine (sweet aftertaste, too :-), but no fluoride or polishing. Then I discovered the SLS connection and bought the SLS free brand (lousy aftertaste ;-p). They also make a sensitive teeth product-you can get it at Amazon. It's been several months now without a canker sore.

[YEA]   Definitely a winner... My mouth ulcers decreased by 75%... Downside is the price however, it's worth the money to be free of the pain that comes with the ulcers.

[YEA]  I suffered from the time I was a child. My mother has the same and now my kids also suffer. about 5 years ago my Dentist told me about recent findings on the link between Sodium Lauryl Sulfite and canker sores. This is a preservative found in almost ALL name brand toothpastes including some of the natural ones. I started using a SLS free Toothpaste and now I get one maybe once or twice per year (and that is usually if my hubby has brushed right before I kiss him). One brand I use is called ____. Very expensive, but worth it. You must be loyal and never use any toothpastes or mouthwashes with S.L. Sulfite. Good Luck

[YEA]  Please please PLEASE try this. It really works. I suffered from multiple outbreaks of canker sores for years and now am down to one or two per year. ____ makes a toothpaste called _____ that is free of the ingredient Sodium Lauryl Sulfate. This ingredient causes canker sores in many. Try this toothpaste, just once (it costs around $7.99 but lasts forever and is well worth it) and you will see a huge difference.

[YEA]  I have had really bad canker sores my entire life. None of the ideas listed here ever worked for me and all of the over the counter meds that you get only made the duration of the sore longer. The ONLY thing that helps me is toothpaste without Sodium Laurel Solphate (sls) - ____. The toothpaste is the best. I also got a paste from my doctor that lessens the severity and the duration.

The only brand that doesn't have SLS is a specific flavor of ____. I can't remember the flavor but read the ingredients. There is an ingredient like it, but not it just be careful it doesn't say Sodium Lauryl Sulfate. I have used the ______ and it gives me horrible canker sores though it does not have SLS. I think it's the Sodium Saccrin in it, not sure. The only thing I've found that doen't make me get them is the _____. And you have to hunt for it. Hope this helps someone!!

[YEA]  First, I use a toothpaste without sodium lauryl sulfate , second I use Clobetasol propionate ointment 0.05% this is by prescription only. This cures canker sores in their tracks. Twice a day usually for only two days and they are gone. I use a q tip for application.

Posted by Scottie (Pelham TN) on 05/18/2006

[YEA]  Use Toothpaste and Mouthwash without Sodium Lauryl sulfate! I get canker sores, sorry did get them if I bit my lip or cut a gum on chips or something. Two weeks of pain! Now I don't get them at all even after a bite or cut gum. I read this cure in some blogs here and there. I started buying ____ toothpaste and mouthwash and this prevents canker sores. I never get them now and I love it!

[YEA]  Turmeric for Canker Sores/Cold Sores

Recently read in Rebecca Wood's "The New Whole Food Encyclopedia" about using turmeric for canker sores. I have low iron which occassionally gives me canker sores so I was searching for a home remedy. Take an 1/8 tsp. of turmeric and just enough drops of water to make a thick paste. Put directly on canker sore before bed and it will be gone by morning. Works well on cold sores too. Beware that turmeric will stain the skin a little (no big deal). I've been referring to this website for years and am glad that I have something to offer back.

[YEA]  Unlit Match for Canker Sores: Oh thank the lord someone put this remedy up.... The to the point story.... Large mouth ulcer with white crust forming, lots of pain, put unlit match on the white part for around 20-30 seconds, not to long in case of further irritation which causes them to grow. Woke up 50% better, repeated same process this morning, ulcer is around 85% gone, will repeat tonight and be done with it, fastest ive ever gotten rid of an ulcer, no more white crust, warning this will sting but the relief it provides after is well worth the pain.
