[|Human|] I have a painful white sore on my lower gum, below my teeth and above my lip. I also had an odd crusty patch just below my lower lip that appeared around the same time. I have smoked more than usual in the past month, but before then I very seldom smoked.
[|AI|]  Thanks for your query. I have gone through your query. The soreness could be an authors ulcer or herpetic ulcers. Nothing to worry. You can take topical anesthetic and analgesics like Anabel gel, apply 3-4times daily before food. If it doe snot work then you can use topical steroids like triamcinolone acetone(0.1%) Apply 3-4times daily after food. Do saline gargling. Do not take tension or stress because This aggravates soreness. I hope my answer will help you. Take care.
