White patches bilaterally behind molars

[steve12345]

I am a 26 year old male that recently noticed white patches behind my molars bilateral. For many years I have occasionally had irritation in those areas that usually resolved in a week. I recently took a look back there and found white. Pictures attached below. I have never used any tobacco products and rarely drink alcohol. I have a dentist appointment scheduled but the suspense is killing me. Any thoughts?

Did you have your wisdom teeth removed surgically? This could be scar tissue in the associated area

Yes, I did have all 4 of my wisdom teeth removed about 8 years ago.
