Inside of my upper lip is swollen
Swelling inside the upper lip can follow biting or irritation, but a blocked minor salivary gland, allergy, infection, or cyst also needs consideration.
The short answer
The inner upper lip contains mucosa, small salivary glands, blood vessels, and connective tissue. Swelling may follow trauma or appear as a mucous cyst, local infection, allergic reaction, or another lesion.

What is the direct answer?
What does this question mean?
A dentist checks for a bite mark, ulcer, tooth edge, draining infection, colour change, and whether the lump is soft, firm, mobile, or fixed. Onset and changes in food, medicine, cosmetics, or dental work help narrow the cause.
What can you do next?
Avoid biting or squeezing the area, use cool water for comfort, and brush gently. Do not puncture a lump or apply household chemicals; photograph changes for comparison.
When should you seek dental care?
Arrange assessment if swelling persists, enlarges, becomes firm, repeatedly returns, or accompanies tooth pain or an ulcer. Sudden lip, tongue, or throat swelling with breathing or swallowing difficulty requires emergency care.
What should you ask the dentist?
Ask whether the swelling is traumatic, salivary, dental, allergic, or infectious and whether imaging, drainage, or tissue sampling is needed.
