<s>[INST] I am 15 years old and have never smoked before. I also never drank any form of alcohol. After having braces for about a year, I notices white patches growing along my mouth (where my teeth touch my gum). I often scrape my braces there and was wondering if this is anything I should be worried about. I have had one patch for around 3 months and another for a week. I did some research and suspect frictional keratosis. However, I am worried it might be something more serious, such as leukoplakia. Can you please help me out? The patches are around an inch long and have a "scale-like" texture. [/INST] Hi! Welcome to Chat Doctor. I read your query. Since you are currently having Orthodontic treatment (braces), there are regions where your toothbrush might not reach for effective cleaning. Also, areas where your braces material impinges continuously onto your gums, leaves a white mark called as Frictional keratitis (as you read too). I would suggest you to visit your Orthodontist and ask him for braces adjustment in that particular area. Also, you can use Orthodontic brushes specially meant for braces cleaning. Use mouthwash regularly as it removes particles from difficult to reach areas of mouth too. Go for oral prophylaxis every 3-6 months. Maintain good oral hygiene and diet. Hope this answer helps. Thank you! </s>
