Where does a mucocele most commonly occur?

  1. Upper lip

  2. Cheek

  3. Lower lip

  4. Tongue

The correct answer is: Lower lip

A mucocele most commonly occurs on the lower lip. A mucocele is a harmless, fluid-filled swelling that forms on the inner part of the lip or the floor of the mouth. It is often caused by damage to a salivary gland duct, leading to the collection of saliva underneath the mucosal tissue. Mucoceles are more frequently found on the lower lip compared to the upper lip, cheek, or tongue.
