What is the most common cause of swelling inside the cheek or on the gums?

A localized, painful swelling is very often caused by a dental abscess from an infected tooth. This requires immediate dental attention.

Can swelling in the mouth be a sign of an allergic reaction?

Yes, a condition called angioedema can cause rapid swelling of the lips, tongue, and inside of the mouth. This can be a medical emergency if it affects breathing.

A mucocele is a common, harmless swelling that occurs when a minor salivary gland is blocked or injured. It looks like a small, soft, bluish or clear blister, often on the inside of the lower lip.

Common Causes of Mucosal Swelling

Dental Abscess: An infection from a tooth root spreading into the surrounding tissues is a primary cause of localized swelling.
Trauma or Injury: Biting your cheek or irritation from a sharp tooth or dental appliance can cause localized swelling.
Blocked Salivary Gland (Mucocele): A common cause of a small, fluid-filled sac, especially on the lower lip.
Allergic Reaction: Foods or medications can trigger an allergic reaction causing swelling.
Oral Cancer: A persistent, firm lump or swelling that doesn't go away should always be evaluated to rule out oral cancer.
