By examining the causes, symptoms, and available interventions, readers will gain a deeper understanding of pericoronitis and learn how to address it effectively, ensuring better oral health outcomes.
The Science Behind Pericoronitis
Bacterial Involvement
Pericoronitis results from bacterial overgrowth in the confined space between the crown of a partially erupted tooth and the surrounding soft tissue. As the tooth erupts, this previously sterile space becomes exposed to the oral microflora, creating an ideal environment for bacterial proliferation. The microbiota associated with pericoronitis is diverse and differs from that found in periodontitis. Studies have shown that bacteria such as Actinomyces oris, Eikenella corrodens, Eubacterium nodatum, Fusobacterium nucleatum, Treponema denticola, and Eubacterium saburreum are present in high levels in pericoronitis lesions. Among these, Fusobacterium species seem to play a significant role in the pathogenesis of acute pericoronitis, with their levels increasing greatly during symptomatic periods.

Inflammatory Process
The presence of these bacteria triggers an inflammatory response in the surrounding soft tissues. As the immune system attempts to combat the infection, it leads to the classic signs of inflammation – redness, swelling, pain, and warmth in the affected area. The gingival tissue overlying the partially erupted tooth, known as the operculum, becomes inflamed and swollen. This further compromises the already limited space, creating a cycle of bacterial growth and inflammation. In some cases, the inflammation can spread to nearby structures, causing trismus (limited mouth opening), facial swelling, and even systemic symptoms like fever and lymphadenopathy. The severity of the inflammatory process depends on various factors, including the virulence of the bacteria involved, the host immune response, and the duration of the infection. Prompt diagnosis and appropriate treatment are crucial in managing pericoronitis and preventing the spread of infection to deeper tissues.
Clinical Presentation of Pericoronitis
Pericoronitis can present as either an acute or chronic condition, each with distinct symptoms. In acute pericoronitis, patients experience sudden onset of severe pain, swelling, and redness in the gum tissue surrounding the affected tooth. They may also report a bad taste in the mouth, difficulty swallowing, and even fever. Pus discharge from the inflamed area is common. In more advanced cases, patients may develop trismus (lockjaw), facial swelling, and swollen lymph nodes in the neck.
Chronic pericoronitis, on the other hand, is characterized by milder, recurrent symptoms that may last for several days at a time. These include dull pain, mild discomfort, and a bad taste in the mouth. The gum tissue around the partially erupted tooth may appear slightly swollen and inflamed.
Differentiating pericoronitis from other dental conditions is crucial for accurate diagnosis and treatment. Dental caries, periodontitis, and periapical abscesses can present with similar symptoms, such as pain and swelling. However, these conditions typically involve the tooth itself or the surrounding bone, rather than the gum tissue. Pyogenic granuloma and peripheral ossifying fibroma, which are reactive lesions that can develop in the gum tissue, may also resemble pericoronitis. Radiographic examination and a thorough clinical evaluation by a dental professional can help distinguish pericoronitis from these other conditions.
Prompt diagnosis and treatment of pericoronitis are essential to prevent the spread of infection and alleviate the patient’s discomfort. Left untreated, pericoronitis can lead to more severe complications, such as deep space infections of the head and neck, which may compromise the airway and require immediate medical attention.
Treatment Strategies for Pericoronitis
Conservative Management
The initial approach to pericoronitis treatment focuses on conservative management strategies. Local debridement and irrigation of the affected area are crucial in removing impacted debris and reducing bacterial load. Dental professionals use sterile solutions such as normal saline, water, chlorhexidine, or hydrogen peroxide to flush the pericoronal space. Mechanical debridement with periodontal instruments further aids in cleaning the infected pocket. Patients are advised to maintain good oral hygiene practices, including proper brushing, flossing, and the use of antibacterial mouthwashes to prevent further buildup and promote healing.
Pain management is another essential aspect of conservative treatment. Oral analgesics, particularly NSAIDs, are the primary method for controlling discomfort associated with pericoronitis. In cases where systemic infection is suspected, antibiotics such as amoxicillin or metronidazole may be prescribed. Erythromycin serves as an alternative for patients with penicillin allergies. Microbial cultures can guide the selection of appropriate antimicrobial agents.

Surgical Interventions
When conservative measures fail to resolve pericoronitis or if the condition recurs, surgical interventions may be necessary. Soft tissue surgery, also known as operculectomy, involves the removal of the infected operculum overlying the erupting third molar. This procedure eliminates the deep pocket between the gingiva and the tooth, reducing the risk of bacterial accumulation. Various techniques, including laser, electrocautery, radiofrequency ablation, or scalpel, can be employed for operculectomy. However, this treatment option is limited to third molars with a favorable eruption position and adequate space for proper eruption.
In cases where the third molar is unlikely to erupt into a functional position and poses an increased risk of persistent infection, tooth extraction may be the most appropriate solution. Removing the problematic tooth eliminates the unreachable, uncleanable space that harbors bacteria and causes chronic pericoronitis. Extraction of the opposing tooth may also be considered as a temporary measure to reduce mechanical trauma and alleviate symptoms when immediate removal of the mandibular third molar is not feasible. Prompt extraction, along with adjunct treatments such as systemic antibiotics and drainage of purulence, expedites recovery and minimizes the risk of infection spread.
Recovery and Aftercare
Following treatment for pericoronitis, proper aftercare is essential to promote healing and prevent recurrence. Patients should closely follow their dental professional’s instructions to ensure a smooth recovery.
Post-treatment Care
Immediately after treatment, patients may experience some discomfort, swelling, and mild bleeding. Over-the-counter pain relievers can help manage pain, while applying an ice pack to the outside of the cheek can reduce swelling. Patients should avoid hot foods and drinks, as well as strenuous activities, for the first 24 hours.
Maintaining good oral hygiene is crucial during the healing process. Patients should gently brush the treated area with a soft-bristled toothbrush and rinse with warm salt water several times a day. Antiseptic mouthwashes may also be recommended to control bacterial growth. If antibiotics have been prescribed, it is essential to complete the entire course, even if symptoms improve.
Patients should attend follow-up appointments as scheduled to allow their dental professional to monitor the healing progress and make any necessary adjustments to the treatment plan. Soft foods are recommended for the first few days, gradually transitioning to a normal diet as comfort allows.

Potential Complications
While most patients recover from pericoronitis without incident, complications can occur. Signs of infection, such as increasing pain, swelling, fever, or discharge, should be reported to the dental professional immediately. In rare cases, the infection may spread to nearby tissues or even the bloodstream, requiring prompt medical attention.
Dry socket, a condition where the blood clot in the extraction site becomes dislodged or dissolves, can cause severe pain and delayed healing. This complication is more common in smokers and those who fail to follow post-treatment instructions. If dry socket occurs, the dental professional will clean the socket and apply a medicated dressing to promote healing.
Adhering to proper post-treatment care and maintaining regular dental check-ups can help prevent complications and ensure a successful recovery from pericoronitis. By working closely with their dental professional and practicing good oral hygiene, patients can look forward to a healthier, pain-free smile.
