White areas on gingiva after treatment

I had a pt whose tissue has white areas on the buccal area after periodontal debridement. Topical lidocaine was used as well as anesthesia. The patient stated that Listerine causes his tissue to slough. https://goo.gl/photos/DoDHBsMnCkg7WHEn8

To me, this looks like a chemical burn. This can happen when chemicals not intended for topical placement are used. Other white lesions that should be included in a differential diagnosis are frictional keratosis, hyperplastic candidiasis, and lichen planus. But again, it looks like a chemical burn to me, not sloughing of tissue caused by Listerine.

If it doesn’t clear up in 2 weeks, the patient should probably have a biopsy.
