First of all, thank you so much for the support and resources on this site. I am so very grateful.

My DH has a white lesion (no bump or thickening of the skin) on the bottom of his tongue that does not heal after accidental biting (or burning) 6 months ago. His biopsy result is mild atypia. His oral/maxillofacial surgeon (DDS & MD) recommends laser ablation in January 2022.

Could someone please shed lights on:

1) What is mild atypia? Is it the same as hyperplasia?
2) What is the recurrence rate? Increased risk of cancer? More follow-ups needed?
3) What should we expect from the laser ablation?

I am not even sure our dental insurance will cover laser ablation on this procedure. We're told this procedure will not be billed to regular medical insurance. We are very confused at this point.

Many thanks.
