"==Merger / relocation== 
 This page has been relocated from mouth ulcer and merged with the previous recurrent aphthous stomatitis page. The previous mouth ulcer page was predominantly about apthous ulcers and not about mouth ulceration in general.  
 *The new mouth ulcer page contains more information about other types of oral ulcerations. ( ) 

  

 ==Ulcers lasting more than 4 weeks== 
 I have definitely had ulcers that last considerably more than a month, on rare occasion more than 2 months.  If I'm alone in this fair enough, but otherwise I think the time frame should be extended, or an 'occasionally longer' added.   

 I, too have had such long-lasting outbreaks of RAS.  If you are unlucky enough to suffer these long-lasting outbreaks, you must make the acquaintance of a good ENT specialist.  He or she will be able to treat these longer outbreaks with steroids, either in oral (methyprednisolone, in this case) or subcutaneously injected form (kenalog, in this case).    

 Ive had once a 2.5 month sore after a severe toungue bit (blood) and practically a toungue piercing. I cant rmemeber how i delt with it.  

 ==chewing gum== 
 My two cents for all the other canker sore sufferers.... For half my life, I chewed gum almost every day, and for that half of my life, I had several canker sores every month.  Stopped chewing gum, and the canker sores have been rare.  (as both curious and masochistic, I will occasionally still chew gum, and have found that the more gum, and the more sugary it is, the more certain that a sore will shortly develop.)  The other bit of advice from my own experience is this: while almost any kind of irritation to my mucus membrance will develop into a sore, I've found that if I can get some mouthwash on it during the first several minutes after the injury, the liklihood of ulcer development is much less.

 ==Rembrandt== 
 ""In some cases, switching toothpastes can prevent mouth ulcers from occurring. Tests have shown that Oral-B Rembrandt Whitening Toothpaste for Canker Sore Sufferers, for example, has been able to reduce the occurrence of ulcers by approximately 80%."" 

 This sounds like advertising copy. 
 
 :It's also correct information. I've been using Rembrandt and noticed a definite decline in frequency of canker sores. Supposedly they have also done controlled studies involving that particular brand.   

 I am using the Rembrandt toothpaste currently, but I have my doubts.  It appears that the 'active ingredient' is simply not having SLS. 

 I changed my toothpaste too (not to Rembrandt) and found I had less canker sores. I think it's more due began brushing and flossing much more regularly than the particular brand of toothpaste. However, this is merely anecdotal evidence. 

 ==Campho-Phenique== 
 The article recommends using Ambesol (spelling?) or Campho-phenique. But the warnings on my tube of Campho-phenique Cold Sore Treatment states, ""If swallowed, get medical help or contact a Poison control center right away."" So if you place this on a canker sore, it would be swallowed - although a small amount. Can anyone provide a answer to the delima? 

 ==Pic anyone?== 
 I was thinking that, I'd soon upload a picture of my recent Canker. Desirable? Appropriate?   

 :That could work. Given the picture on Erection I think a picture of a mouth ulcer would comparatively be well in order   

 ::Let me wade through the licensing literature first. Is it me, or does it seem like we're the only ones who care about this article, ATM? -   

 :::Ouch, that looks painful. I first came across this article suffering from an ulcer myself, so... I guess this is mostly interesting to sufferers! And we suffer for our art. Good picture though.   
 ::::As you can probably guess, I came here when I was afflicted as well. What really threw me was the lack of distinction between a Canker sore and a cold sore. Would you like to insert this distinction? You really think it was good? It was hard getting the autofocus to work right.
