Yes, you're right: in my case, EC started at 17 and now I'm 33.
No miraculous method found at this point, but as I said in the previous posts, applying some Eucalyptus honey may help to manage this condition. Brush also your teeth, mouth, gums very often. Use small scissors to cut the curved dead skin.
I have not the feeling that my english has improved a lot over the years... Thank you !
