Pericoronitis Treatment
Pericoronitis Treatment is a specialized dental service provided by the board-certified specialists at Aloha Dental Specialty Center in Beaverton, OR. Removing the gum tissue flap over a partially erupted tooth to stop recurring infections.
That Gum Flap Over Your Back Tooth Is Not Going Away on Its Own
When a tooth — typically a lower wisdom tooth or a second molar — partially erupts, a flap of gum tissue often remains draped over the biting surface. This flap is called an operculum. It creates a trap: food debris, bacteria, and plaque accumulate in the pocket between the operculum and the tooth, but they cannot be cleaned out because the flap seals the space. The result is pericoronitis — a painful, recurring infection that causes swelling, difficulty opening the mouth, bad taste, and sometimes spreading facial infection.
An operculectomy surgically removes the operculum, eliminating the pocket and exposing the tooth surface for normal cleaning. At ADSC, we evaluate each case to determine whether operculectomy or extraction is the better solution. If the tooth is well-positioned and has room to fully erupt, removing the operculum allows it to function normally. If the tooth is impacted or poorly angled and will never fully erupt, the gum flap is merely a symptom of the real problem, and extraction is the definitive treatment.
The procedure is quick — typically 15-20 minutes under local anesthesia. Dr. Ostovar excises the operculum using a scalpel or electrosurgical unit, debrids any granulation tissue beneath it, and irrigates the area. Sutures are not always necessary. Healing is rapid, with the surgical site closing within 1-2 weeks. Patients experience significant relief from the cycle of recurrent infections. In cases where pericoronitis has already progressed to significant swelling and trismus, we may prescribe a short course of antibiotics before the operculectomy to reduce acute inflammation.

Recovery & Healing Timeline
Understanding the healing process helps you plan ahead and follow post-operative instructions for the best possible outcome.
First 48 Hours
Mild swelling and tenderness are normal. Apply ice packs in 20-minute intervals and take prescribed or over-the-counter anti-inflammatory medication. Eat soft foods and avoid the surgical site when chewing.
Days 3 to 7
Swelling peaks around day three and then improves. The tissue begins closing over the surgical site. Continue with soft foods and use any prescribed antimicrobial rinse. Most patients return to normal activities during this phase.
Long-Term Healing
Surface tissue heals within two to three weeks. Bone integration and deep healing continue for three to six months. Avoid smoking, follow up as scheduled, and maintain good oral hygiene throughout recovery.

Pericoronitis: The Microbiology Under the Gum Flap
The space between the operculum and the tooth crown is a warm, moist, anaerobic environment — ideal for pathogenic bacteria. The microbiome of pericoronitis is dominated by strict anaerobes: Prevotella intermedia, Fusobacterium species, Peptostreptococcus, and Actinomyces. These organisms produce enzymes that break down tissue, volatile sulfur compounds that cause foul odor, and inflammatory mediators that trigger the body's immune response. The repeated cycle of food impaction, bacterial overgrowth, immune response, partial resolution, and recurrence is the hallmark of untreated pericoronitis. Operculectomy breaks this cycle by eliminating the sheltered environment these bacteria depend on.
Why Choose a Specialist?
The clinical judgment in operculectomy lies in the decision: operculectomy or extraction? Removing the operculum over a tooth that has no room to erupt fully — or that will re-cover with tissue — wastes the patient's time and money. The surgeon must evaluate the eruption path, the available space in the arch, the angulation and depth of the tooth, and the likelihood that the operculum will recur. This assessment requires radiographic evaluation (ideally CBCT) and clinical experience with eruption patterns. When the tooth is a candidate for retention, operculectomy is a conservative, effective solution. When it is not, extraction is the honest recommendation.

A Note from Your Dental Team
In my experience, the patients who get the best results from pericoronitis treatment are those who come in with realistic expectations and follow their post-treatment instructions carefully. I’d rather spend extra time explaining what to expect than have a patient be surprised later.
“Every patient I see has a different story, a different set of concerns, and a different definition of what ‘success’ looks like. That’s why I don’t believe in one-size-fits-all treatment plans. When you come in for a consultation, I’ll listen first, examine second, and recommend third.
I also won’t recommend a procedure you don’t need. If your tooth can be saved with a filling instead of a crown, I’ll tell you that. If watchful waiting is appropriate, I’ll explain why. My job isn’t to sell treatment — it’s to give you my honest clinical judgment so you can make an informed decision.
If you have questions about whether this treatment is right for you, or if you’ve been told you need this procedure by another dentist and want a second opinion, call us at (503) 822-0096. We’re happy to take the time to explain everything — no rush, no pressure.”

I know many patients feel anxious about dental procedures — you’re not alone in that. What I hear most often after treatment is: “That was so much easier than I expected.” We’re here to make this as comfortable as possible for you.
Typical Healing Timeline:
Days 1-3: Initial healing, mild swelling managed with ice and medication. Days 4-7: Swelling subsides, gradual return to normal diet. Weeks 2-4: Soft tissue heals completely. Months 2-6: Bone remodeling and full integration (for surgical procedures). Individual recovery varies — we provide detailed post-op instructions specific to your procedure.

Frequently Asked Questions
What is an operculectomy?
An operculectomy is the surgical removal of the gum tissue flap (operculum) that covers a partially erupted tooth. By removing this tissue, the tooth is exposed, the bacterial pocket is eliminated, and the cycle of recurring pericoronitis infections is broken.
What is pericoronitis?
Pericoronitis is an infection of the gum tissue surrounding a partially erupted tooth, most commonly a lower wisdom tooth. It causes pain, swelling, bad taste, difficulty opening the mouth, and sometimes spreading infection. It tends to recur because the gum flap recreates the bacterial pocket between episodes.
Is operculectomy painful?
The procedure is performed under local anesthesia and is painless during surgery. Post-operative discomfort is mild — more of a soreness than sharp pain. Over-the-counter ibuprofen is usually sufficient. The surgical site heals quickly, and most patients feel relief from the chronic pericoronitis symptoms within a few days.
When is operculectomy better than extraction?
Operculectomy is appropriate when the partially erupted tooth is well-positioned, has room to fully erupt, and is otherwise healthy. If the tooth is impacted, tilted, decayed, or will never have space to erupt fully, extraction is the better long-term solution because the operculum will likely recur.
How long does an operculectomy take?
The procedure typically takes 15-20 minutes, including anesthesia. It is one of the quickest procedures in oral surgery. If combined with debridement of infected tissue or if electrosurgery is used for hemostasis, it may take slightly longer.
Can the gum flap grow back after operculectomy?
If enough tissue is removed and the tooth has room to fully erupt, the operculum should not recur. However, if the tooth remains only partially erupted and tissue has room to re-drape over the crown, recurrence is possible. This is why proper case selection — ensuring the tooth can fully erupt — is essential before choosing operculectomy over extraction.
Do I need antibiotics before or after an operculectomy?
If you are currently experiencing active pericoronitis with significant swelling, we may prescribe antibiotics for 1-3 days before the procedure to reduce acute inflammation. After the operculectomy, antibiotics are usually not necessary if the tissue is healthy and healing normally. Chlorhexidine rinses may be prescribed for the first week.
How do I care for the site after operculectomy?
Rinse gently with warm salt water or prescribed chlorhexidine rinse 2-3 times daily for one week. Eat soft foods for the first few days. Keep the area clean with gentle brushing once the initial tenderness subsides (usually after 2-3 days). Avoid crunchy or sharp foods that could irritate the healing tissue.
Can operculectomy be done on teeth other than wisdom teeth?
Yes. Although wisdom teeth are the most common location, operculectomy can be performed on any partially erupted tooth with an overlying gum flap — including second molars, premolars, or even canines that are erupting slowly through the tissue.
How much does an operculectomy cost?
Operculectomy is one of the less expensive oral surgery procedures. The fee depends on the complexity and whether additional treatment (debridement, biopsy of the tissue) is performed. Most dental insurance plans cover the procedure. We provide a specific estimate during your consultation.
What happens if I just keep treating pericoronitis with antibiotics?
Repeated antibiotic courses without definitive treatment (operculectomy or extraction) lead to antibiotic resistance, recurrent episodes that may become more severe over time, chronic bone loss around the tooth, and risk of spreading infection during a future episode when antibiotics are less effective.
Is an operculectomy done with a scalpel or laser?
Both methods are used. At ADSC, we typically use a scalpel for precision excision, sometimes supplemented with electrosurgery for hemostasis. Laser operculectomy is also available. The choice depends on the tissue characteristics and the extent of removal needed. All methods achieve the same end result.
Can pericoronitis spread and become dangerous?
Yes. Untreated pericoronitis can spread to the submandibular space, parapharyngeal space, or retropharyngeal space — potentially compromising the airway. While this progression is uncommon, it is serious when it occurs. Definitive treatment of the operculum prevents this risk entirely.
I have trouble opening my mouth because of the gum flap infection. Is this normal?
Limited mouth opening (trismus) is a common symptom of pericoronitis. The infection and inflammation involve the muscles of mastication that are adjacent to the posterior mandible. Trismus typically improves within a few days of starting antibiotics, and resolves fully after operculectomy or extraction eliminates the source.
Do I need IV sedation for an operculectomy?
Operculectomy is a minor, quick procedure that is well-tolerated under local anesthesia alone. IV sedation is available but rarely necessary specifically for operculectomy. If the operculectomy is being combined with wisdom tooth extraction, sedation may be used for the extraction portion.
