What Is A Mucous Cyst
A mucous cyst, also known as a mucocele, is a fluid-filled swelling that occurs on the lip or the mouth. The cyst develops when the mouth’s salivary glands become plugged with mucus. Most cysts are on the lower lip, but they can occur anywhere inside your mouth. They’re usually temporary and painless. However, cysts can become permanent if they’re not treated.
What causes mucous cysts?
Mucous cysts are most commonly caused by trauma to the oral cavity, such as:
- lip biting (most common cause)
- cheek biting
- piercings
- accidental rupture of a salivary gland
- adjacent teeth causing chronic damage
Poor dental hygiene and a habit of lip or cheek biting due to stress can also put you at higher risk for developing mucous cysts. Some people develop these cysts as a bad reaction to tartar-control toothpaste.
Mucous cysts are most common in people ages 10 to 25. However, these cysts can occur in people of all ages. They also happen equally in both females and males.
The symptoms of a mucous cyst vary by how deep the cyst lies within the skin and how often the cysts occur. Most cysts are not painful, but they can be uncomfortable. Frequent cysts can become painful over time.
Symptoms of cysts near the surface of the skin include:
- raised swelling
- bluish color
- softness
- lesions less than 1 centimeter in diameter
Symptoms of cysts deeper within the skin include:
- rounded shape
- whitish color
- tenderness
How are mucous cysts treated?
Treatment is based upon the severity of the mucous cyst. Sometimes cysts may not require treatment and will heal on their own over time. Superficial cysts often resolve on their own. To prevent infection or tissue damage, do not try to open or remove cysts at home. Frequent or recurring cysts may require further medical treatment.
