I have a mouth ulcer that has turned green. is that bad or is it okay? i have read that they should be red, yellow, or gray. does green mean it is infected or something?

Idaho : Idaho falls, green is not normal. It is so not normal that i can't even guess what it is. I know it has been stated but see your dentist. Maybe pictures on this site would be helpful. Hope this is helpful, michael i. Wollock, dmd, agd fellow dentistry at suburban square 610-649-0313.

Without : Without looking at you lesion it will be difficult to know, depends on how long you've had this greenish ulcer, any ulcer is a manifestation of an infection. So please go visit your dentist and let him decide the type of ulcer you have. Good luck!
