Dental Health, Sore on the Inside of Upper Lip
Question: I have a white sore on the right side of my upper lip in my mouth. My tooth is rubbing on it and making it hurt worse. How do I get rid of it?
Answer: Sounds like you may have a canker sore. Canker sores are small, red or white, shallow ulcers occurring on the tongue, soft palate, or inside the lips and cheeks. They are quite painful, and usually last 5-10 days. Treatment is directed toward relieving discomfort and guarding against infection. A topical corticosteroid preparation such as triamcinolone dental paste (Kenalog in Orabase 0.1%) is helpful. Consider consulting a physician if a mouth sore has not healed within two weeks.
