What is the direct answer?
A swollen area inside the upper lip is usually caused by irritation, a blocked minor salivary gland, an ulcer, or a local infection.
What does this question mean?
The inner upper lip can swell when its lining is irritated, a minor salivary gland duct is blocked, or nearby tissue is inflamed.
What can you do next?
This symptom refers to enlargement of the soft mucosa between the upper teeth and the outer lip. Biting, a sharp tooth, a canker sore, dental infection, allergy, or a mucus-filled cyst can produce it.
When should you seek dental care?
Rinse gently with warm salt water, avoid biting or rubbing the area, and choose soft foods while you observe it. Do not puncture a lump or apply concentrated chemicals to the mucosa.
What should you ask the dentist?
Arrange an examination if the swelling persists, returns, becomes painful, drains, or is associated with toothache or fever. Seek urgent care for rapidly increasing facial swelling or trouble breathing or swallowing.
