<s>[INST] I have annoying rough spots of dead skin on my inner cheeks. I brush at least twice a day very well an use mouthwash . Im 16 an i play football and my ice hockey season just started. In both sports I wear a mouthguard which i think may be part of the problem. How can i get rid of these little bits of deadskin? I find them very annoying! [/INST] Hello there ...What exactly do you mean by rough spots or dead skin? How does it look? If you have redness or purplish discoloration over your mucosa, that can be attributed to the mouth-guard you use...Clinical evaluation is required to see the extension and nature of the mucosa....Kindly consult a Oral and Maxillofacial Surgeon or an experienced dental surgeon for further management. </s>
