[|Human|] Hi Doctor..... I have black patches over the walls of cheeks inside mouth for nearly 1 year. I cannot eat any spicy or sweet stuff. I burns like hell. What is the reason. I tried so many medications and nothing worked. Due to this problem, my gums bleeds when I brush and mouth burns when there is paste in my mouth. Thereofre, I am unable to brush my mouth properly and I get bad odour.
[|AI|]  Hello, Thanks for consulting ChatDoctorRead your query as you have black patches on cheeks with burning sensation don't worry this patch can be due to lichen plans, licensed reaction for this I will suggest you to consult oral surgeon for examination of patches on buccal mucosa and oral prophylaxis for bad breath and bleeding gums. In meantime you can do warm saline rinses, and take medicine Antioxidant like Lycopene, and vitamin A, you can apply ointment like Tess buccalmpaste or Heal plus on cheek for burning sensation. Hope this will help you.
