I have a canker sore! Make it go away? Plz?

I don't think there is a specific way to just get rid of it... if there is let me know! But to not make it angry and eat your siblings you should stay away from food with acid like pineapple, oranages, gfriuts, ketchup, mustard stuff like that, it just makes it worse and can actually cause them to break out, if and when you eat a lot of it! Well good luck hope u get better soon! ;o)
