An oral mucocele is a common, harmless, fluid-filled swelling that appears in the mouth. It often presents as a bubble-like lump.
What is a Mucocele?
A mucocele is a cyst-like swelling caused by an accumulation of mucus from a minor salivary gland. It typically appears as a transparent, soft, round, or dome-shaped lump. While mucoceles can occur anywhere in the mouth where minor salivary glands are present, such as the tongue or palate, they are most frequently found on the inside of the lower lip, accounting for an estimated 96% of cases.
The primary causes of mucoceles include trauma to the oral cavity, such as accidental lip biting, lip-sucking habits, or piercings that rupture a salivary gland duct. This damage or blockage prevents saliva from draining properly, leading to its buildup in the surrounding tissues. Less commonly, an obstruction of the glandular duct, such as by a salivary stone, can also lead to mucocele formation.
Typical Resolution Timeline
Many mucoceles resolve spontaneously without intervention. The typical timeframe for resolution ranges from a few days to six weeks. During this period, the mucocele may rupture on its own, releasing the accumulated fluid, and then heal.
The time it takes for a mucocele to go away can be influenced by several factors. The size of the lesion plays a role, with smaller mucoceles often resolving more quickly. Its location and whether the area is subjected to repeated trauma, such as continued lip biting or cheek chewing, can also affect the healing process and may delay resolution or lead to recurrence.
When to Seek Professional Guidance
While many mucoceles clear up on their own, it is advisable to consult a dentist or doctor if the lesion persists beyond six weeks. Professional guidance is also recommended if the mucocele is large, causes pain, frequently recurs, or interferes with daily activities like eating or speaking. These symptoms might indicate a need for treatment or further investigation.
Attempting to self-treat a mucocele, such as trying to pop it, is not recommended. This can increase the risk of infection and cause further damage to oral tissues, potentially leading to scarring or recurrence. A healthcare professional can accurately diagnose the condition and recommend appropriate management, which may include observation, minimally invasive procedures like laser therapy, or surgical removal of the cyst and associated salivary gland.
