A flap of gum, called an operculum, can form over your wisdom tooth, especially if it's impacted or only partially erupted.
Understanding the Operculum
When a wisdom tooth doesn't fully emerge from the gums, a flap of gum tissue can cover a portion of the tooth. This is the operculum.
Reasons for Gum Over Wisdom Tooth
- Partial Eruption: Wisdom teeth often struggle to erupt completely due to lack of space in the jaw.
- Impaction: The tooth may be blocked by other teeth or bone, preventing full emergence.
- Pericoronitis: Food particles and bacteria can become trapped under the operculum, leading to infection (pericoronitis).
Potential Problems with Gum Over Wisdom Tooth
- Infection (Pericoronitis): Trapped debris under the gum flap creates an environment for bacteria to thrive, causing inflammation, pain, swelling, and even pus formation.
- Difficulty Cleaning: The flap makes it difficult to properly clean the area, further contributing to bacterial buildup.
- Pain and Discomfort: The inflammation and pressure from the erupting tooth can cause significant pain.
What To Do
Consult with a dentist or oral surgeon. They can assess the situation and recommend the best course of action, which may include:
- Cleaning: Thorough cleaning of the area under the operculum.
- Antibiotics: If there's an active infection, antibiotics may be prescribed.
- Operculectomy: Removal of the gum flap (operculum).
- Tooth Extraction: In many cases, extraction of the wisdom tooth is recommended to prevent recurring problems.
