Inner upper lip sore
An upper inner-lip sore is often minor trauma, a canker sore, or irritation, but a persistent, recurrent, or unusual lesion needs examination.
The short answer
The inner lip is oral mucosa and can be injured by biting, sharp teeth, braces, or hot food. A painful ulcer differs from a painless lump caused by a salivary or other tissue change.
What is the direct answer?
What does this question mean?
Rinse gently, avoid spicy or rough foods, and do not pick or burn it. Check for a sharp edge or appliance and arrange assessment if the cause is unclear or it recurs.
What can you do next?
Seek prompt care if it persists, enlarges, hardens, bleeds, causes numbness, or occurs with neck swelling or swallowing difficulty.
When should you seek dental care?
Ask whether it is trauma, ulcer, salivary swelling, infection, or another tissue change, and whether a tooth or appliance is irritating it.
What should you ask the dentist?
The inner lip is oral mucosa.
