What is the direct answer?
Burning or tingling of the upper lip can involve irritated skin, a cold sore, nerve symptoms or a dental source.
What does this question mean?
A tingling patch followed by small fluid-filled blisters can fit herpes labialis, while dry, cracked or newly exposed skin points toward irritation. Dental anesthesia, trauma, an inflamed tooth or irritation of branches of the trigeminal nerve can produce altered sensation around the lip.
What can you do next?
Note when the sensation began, whether a rash or blister appears, and whether dental work, a new cosmetic product or an injury preceded it. Keep irritated skin clean, stop a suspected new product, and avoid touching or popping any blister.
When should you seek dental care?
Seek prompt care if symptoms persist, recur, follow dental treatment, or occur with tooth pain, facial swelling or numbness. Get emergency help for sudden facial weakness, speech trouble, severe headache, or swelling that affects breathing or swallowing.
What should you ask the dentist?
Ask whether a tooth, recent procedure, oral tissue or nerve distribution explains the sensation and whether examination or imaging is indicated. Mention every medicine, skin product and recent dental injection.
