My tongue looks like I have been chewing on the sides. Noticed 2 weeks ago after eating but still there. Doesn't hurt but concerned?

Yes/no. Yes = due to long term chewing on it can cause a calluses (whitish) which in turn can become precancerous by definition. No = No worries because I have never seen it get to that stage or there are no clinical cases on record that this has happened due to repeated chewing.
