Just recently, I discovered a yellowish/whitish spot in my mouth, similar to what looks like a pimple. It is sore, and it burns when I eat acid like foods such as tomatoes, ketchup, or something salty. It's on my inner lip, across from about where my canine tooth is.
It has a few red marks around it, which were not there before. It's getting worse. I don't know what it is, or how to treat it. My boyfriend thinks it's caused by salt, but I think I should use a salt water solution/mouth wash for it.
Can anyone help me out?
