Gum Flap Over Wisdom Tooth

When wisdom teeth start to emerge, a common issue many face is the development of a gum flap over wisdom tooth, a condition that can lead to discomfort, swelling, and sometimes infection.

This article aims to shed light on everything you need to know about gum flaps over wisdom teeth, including why they occur, the symptoms to watch out for, and the best practices for treatment and prevention.

What is a dental operculum?

A dental operculum is a flap of tissue over the crown of a tooth, most commonly seen over the third molars, also known as wisdom teeth. This tissue can become a problem when it partially covers a tooth that is not fully erupted, creating a pocket where food and bacteria can accumulate, leading to pericoronitis.

Pericoronitis is an inflammation of the operculum and surrounding tissues, often causing pain, swelling, and sometimes infection. In some cases, the operculum may need to be removed surgically, especially if recurrent infections occur or if it interferes with oral hygiene practices.

Why do wisdom teeth have gum flaps?

Wisdom teeth, or third molars, often have gum flaps (dental opercula) because they are the last teeth to erupt in the mouth, usually emerging in the late teenage years or early adulthood.

By the time wisdom teeth start to come in, the jaw may not have enough space to accommodate them due to the presence of the other 28 adult teeth.

This lack of space can cause wisdom teeth to erupt partially or at an angle, leading to the formation of gum flaps over parts of the teeth.

These gum flaps can create pockets between the tooth and the gum, which are difficult to clean and can trap food particles and bacteria.

This environment is conducive to the development of infections and inflammation, such as pericoronitis.

The presence of gum flaps around wisdom teeth is a common reason for discomfort and oral health issues, often leading to the recommendation to remove the wisdom teeth to prevent further problems.

What does gum flap over wisdom tooth look like?

Pericoronitis, an inflammation of the gum tissue surrounding a partially erupted tooth (usually a wisdom tooth), presents with several visible signs and symptoms that can help in its identification.

Here’s what pericoronitis typically looks like:

Gum Flap Over Wisdom Tooth
  • Swollen Gum Tissue: The gum around the affected tooth appears swollen and may protrude over the tooth. This swelling can sometimes extend to affect the cheek and make the face appear asymmetrical.
  • Redness: The inflamed gum tissue often appears redder than the surrounding healthy gum tissue. This redness is a sign of inflammation and infection.
  • Pus: In cases where an infection is present, you might see pus oozing from around the affected tooth. This can be a sign of an abscess forming under the gum.
  • Gum Flap (Operculum): Over a partially erupted wisdom tooth, a flap of gum tissue, known as an operculum, may be visible. This gum flap can trap food particles and bacteria, leading to inflammation.
  • Difficulty Opening the Mouth: Although not a visual sign, individuals with pericoronitis may have difficulty opening their mouth fully due to the pain and swelling, which can be noticeable in their movements and facial expressions.
  • Bad Breath or Taste: While not directly visible, a persistent bad taste in the mouth or bad breath can accompany the visible signs of pericoronitis due to the presence of bacteria and possibly pus.

Is it normal to have gum flap over your wisdom tooth?

Having a gum flap, or operculum, over a wisdom tooth is relatively common, especially during the process of wisdom teeth eruption.

This occurs when a wisdom tooth (third molar) does not fully emerge into its expected position in the mouth, leaving part of the tooth covered by a flap of gum tissue.

This situation is most common in late adolescence or early adulthood, typically between the ages of 17 and 25, when wisdom teeth usually start to emerge.

While the presence of a gum flap over a wisdom tooth is normal in the sense that it happens to many people, it can lead to complications such as pericoronitis, which is an inflammation of the gum tissue around the crown of a partially erupted tooth.

The trapped food particles and bacteria under the gum flap can cause infection and swelling, leading to pain and discomfort.

Try to maintain good oral hygiene and have regular dental check-ups, especially during the years when wisdom teeth are expected to erupt.

Is it a problem to leave the gum flap over a wisdom tooth?

Leaving a gum flap (operculum) over a wisdom tooth can potentially lead to problems, primarily due to the difficulty in maintaining proper oral hygiene in that area.

The space under the gum flap can easily trap food particles and bacteria, creating an environment conducive to infection and inflammation, known as pericoronitis.

  • Risk of Infection: The most common issue associated with a gum flap over a wisdom tooth is pericoronitis, an infection that can cause pain, swelling, and in severe cases, spread to other parts of the face or neck.
  • Difficulty in Cleaning: The presence of a gum flap makes it challenging to clean the area effectively, increasing the risk of tooth decay and gum disease not only for the wisdom tooth but also for the adjacent teeth.
  • Pain and Discomfort: Food particles and bacteria trapped under the gum flap can lead to irritation, causing pain and discomfort. This can affect eating, speaking, and overall quality of life.
  • Cyst Formation: In rare cases, cysts or tumors can develop around the impacted wisdom tooth, potentially leading to damage to the jawbone and surrounding teeth. Regular monitoring by a dental professional is essential to detect such issues early.
  • Chronic Conditions: If left untreated, pericoronitis can become a chronic condition, leading to repeated episodes of pain and infection.

Given these potential problems, consult with a dentist or oral surgeon to evaluate the condition of your wisdom teeth and the surrounding gum tissue.

In some cases, the recommended course of action might be to remove the gum flap or extract the wisdom tooth to prevent further complications.

Treatment for dental operculum

Treatment for a dental operculum, or the gum flap over a wisdom tooth, depends on the symptoms and problems it causes. Here are the common treatment options:

  • Improved oral hygiene: Initially, improving oral hygiene around the affected area can help manage mild symptoms. This includes thorough brushing, using an antiseptic mouthwash, and possibly using a water flosser or an interdental brush to remove food particles and bacteria trapped under the gum flap.
  • Antibiotics: If an infection is present, a dentist may prescribe antibiotics to reduce the bacterial infection. However, antibiotics are a temporary solution and do not address the underlying cause.
  • Operculectomy: This is a minor surgical procedure to remove the gum flap. It is often recommended if the operculum is causing recurrent infections (pericoronitis) or other issues. The procedure is typically straightforward and can be performed under local anesthesia.
  • Wisdom tooth removal: If the problems associated with the dental operculum are severe or recurrent, or if the wisdom tooth is impacted (not fully erupted and misaligned), extraction of the wisdom tooth might be the best solution. Removing the tooth eliminates the risk of future infections and resolves the issue permanently.
  • Pain management: For temporary relief of symptoms, over-the-counter pain relievers such as ibuprofen or acetaminophen can be used. Rinsing with warm salt water may also help reduce pain and swelling.

What is an Operculectomy?

Operculectomy is a minor surgical procedure aimed at removing the operculum, which is the flap of gum tissue covering a partially erupted tooth, typically a wisdom tooth (third molar).

This procedure is often considered when a patient experiences recurrent episodes of pericoronitis, an inflammation of the gum tissue around the crown of a partially erupted tooth, which can lead to pain, infection, and other complications.

The primary goal of an operculectomy is to eliminate the gum flap that traps food particles and bacteria, thereby reducing the risk of infection and making it easier to clean the area around the tooth.

By removing this source of potential infection, patients can experience relief from the painful symptoms associated with pericoronitis and prevent further episodes.

Procedure Overview

An operculectomy is typically performed under local anesthesia, which numbs the area around the affected tooth to ensure the patient does not feel pain during the procedure.

The dental surgeon or oral surgeon will then carefully cut away and remove the gum flap using surgical instruments. The exact technique and instruments used can vary depending on the specifics of the case and the surgeon’s preference.

Aftercare for removal of gingival operculum

After the removal of a gingival operculum, typically through an operculectomy or as part of a wisdom tooth extraction, proper aftercare is crucial for healing and preventing complications.

Here are general guidelines for aftercare following the removal of a gingival operculum:

  • Pain management: Pain after the procedure is common. Your dentist or surgeon may recommend or prescribe pain relievers. Over-the-counter pain medications like ibuprofen (Advil, Motrin) or acetaminophen (Tylenol) can also help manage pain and reduce inflammation. Follow the dosage instructions provided by your healthcare provider.
  • Bite on gauze: Immediately after the procedure, you’ll likely be asked to bite gently on a piece of sterile gauze to control bleeding. Change the gauze as directed by your dentist or oral surgeon, usually every 30 to 60 minutes, until the bleeding stops.
  • Ice packs: Apply ice packs to the outside of your face where the surgery was performed to reduce swelling and bruising. Do this for 15-20 minutes at a time during the first 24 hours after the procedure.
  • Oral hygiene: Keeping your mouth clean is essential for healing. You may be advised to rinse your mouth gently with warm salt water (1/2 teaspoon of salt in a cup of warm water) several times a day, especially after meals, to keep the area clean and reduce the risk of infection.
  • Diet: Stick to a soft or liquid diet for the first few days after the procedure. Avoid hot, spicy, crunchy, or hard foods that might irritate the wound or get trapped in it. Foods like soups, yogurt, applesauce, and smoothies are good options.
  • Avoid certain activities: Avoid smoking, using a straw, or spitting vigorously for at least 24-48 hours after the procedure, as these actions can dislodge the blood clot that forms in the socket, leading to increased bleeding or the development of a painful condition known as dry socket.
  • Rest: Limit physical activity for the first few days after the procedure to reduce bleeding, swelling, and pain.
  • Follow-Up: Attend any follow-up appointments with your dentist or oral surgeon to ensure proper healing. If stitches were placed, they might need to be removed, or they may dissolve on their own, depending on the type used.
  • Watch for complications: Contact your dentist or oral surgeon if you experience excessive bleeding, severe pain, swelling that worsens after 2-3 days, signs of infection (such as fever, foul taste, or pus), or any other concerns.

What to expect from an operculectomy

An operculectomy involves the surgical removal of the gum flap (operculum) over a partially erupted tooth, typically a wisdom tooth. Expect minor surgery under local anesthesia, with possible sedation.

Post-procedure, there may be discomfort, swelling, and a brief recovery period. Pain management includes over-the-counter medications and ice packs.

Oral hygiene is important, involving gentle rinsing with salt water. Dietary adjustments to soft foods may be necessary. Follow-up visits ensure proper healing. Complications are rare but can include infection or delayed healing. Recovery typically takes a few days to a week.

Is it only involved with wisdom teeth?

An operculectomy is most commonly associated with wisdom teeth (third molars) because these are the teeth most likely to have issues with partial eruption and the formation of an operculum, or gum flap.

Yet, the procedure is not exclusive to wisdom teeth. It can be performed on any tooth that has an operculum causing problems, such as infection (pericoronitis), difficulty with oral hygiene, or discomfort.

While it’s less common for other teeth to require an operculectomy, the technique can be applied wherever there is a need to remove a gum flap over a partially erupted tooth to improve oral health and prevent further complications.

FAQ on gum flap over wisdom tooth

Will gum flap over wisdom tooth go away?

A gum flap over a wisdom tooth may not go away on its own, especially if the tooth remains partially erupted. In some cases, if the wisdom tooth fully emerges into its correct position, the gum flap could reduce or resolve. Persistent flaps often require dental intervention, such as improved oral hygiene, medication, or surgical procedures like operculectomy, to prevent complications like pericoronitis.

Why is my gum growing over my wisdom tooth?

Your gum is growing over your wisdom tooth likely because the tooth is partially erupted, creating a flap of gum tissue known as an operculum. This can happen when there isn’t enough space in the mouth for the tooth to fully emerge, leading to the gum partially covering the tooth.

Can pericoronitis go away on its own?

Mild cases of pericoronitis can sometimes resolve on their own with improved oral hygiene, such as thorough brushing and rinsing with warm salt water. More severe cases, on the other hand, often require dental intervention, including professional cleaning, antibiotics, or surgical procedures. Without proper treatment, pericoronitis can recur or worsen.

How do you treat a gum flap?

Treating a gum flap over a wisdom tooth involves good oral hygiene, rinsing with salt water or antiseptic mouthwash, and possibly antibiotics for infection. In persistent or severe cases, a dentist may recommend an operculectomy to remove the flap or extraction of the wisdom tooth.
