What does this look like?

I’ve had this white lesion on the roof of my mouth for at least two years without noticing any growth getting it biopsied next month but wondering if anyone had some ideas regarding what it could be? My dentist thinks possibly scar tissue however my oral surgeon didn’t really express much of what he thought

Could be scar tissue. Doesn't look sinister. Wait for the biopsy results
