What is a Mucocele?

Some patients will come to our Lynnwood dentistry clinic with concerns about unusual bumps or discolorations in their mouths. One of these is known as a mucocele. These typically manifest as a small, round bump, between two and ten millimeters in diameter, either pearly white or light bluish in color. They may appear anywhere on the inside of your bottom lip, on your gums, or on the roof or floor of your mouth.

Mucoceles are the result of a salivary duct getting blocked or damaged. Maybe you experienced some trauma on your face, or maybe you have a habit of biting or sucking on your lip or cheek too much. The good news is that they’re generally painless and harmless, and will likely go away without treatment, but your dentist can help you if they start to grow or become bothersome.
