Thank you for your question.
Sloughing of the skin as you describe it normally is a result of a contact allergy to something you ate or some kind of medication or mouthwash you placed in your mouth. Try to correlate the sloughing incidents with anything you are ingesting that could be the cause. I have the same reaction to a certain brand of whitening toothpaste and will feel the surface layer of skin start to peel off after about one hour of using that particular brand. There is a specific ingredient in something you are ingesting that is the source of the allergy. I hope this answers your question. Please get back to me if you have any further questions or comments regarding this matter and I will get right back to you.

Have you changed your diet at all? Are you eating anything different, spicy foods, acidic foods such as lemons, raw tomatoes? Any nuts, strawberries? These are known to be particularly allergy inducing foods.

This is what causes tissue sloughing in the majority of cases. If you can't think of what might be causing this,you should have an Oral Surgeon take a look at the area next time the tissue sloughs off, just to be sure. If he thinks it looks suspicious, he will take a biopsy and have the tissue sample analyzed. Oral cancer does not usually manifest in this manner however. I hope this helps.
