A few days ago, I got this pain in my mouth .inner cheek and thought it was canker sore , but when i felt it with my tongue it was more like a line instead of circle like canker sore. So, I looked in the mirror and it looks like a nerve. while line i have never seen.What is it?
Hello, the line running in the inner cheek is known as "line Alba" common in most of the individual due chronic irritation by the teeth when they occlude. don't worry until there is pain or ulceration. Take care.
