Subperiosteal Abscess Dental: Understanding Its Implications and Treatment

A subperiosteal abscess dental condition is more than just a simple toothache; it’s an acute infection that could threaten oral health. Located beneath the periosteum layer that covers the jawbone, this abscess poses unique challenges and requires immediate attention. What exactly causes these abscesses, and how are they best treated to prevent further health complications?

Delve into the complexities of diagnosing and managing subperiosteal abscesses with us as we explore effective strategies to combat this serious dental condition.

What is a Subperiosteal Abscess?

A subperiosteal abscess is a serious dental condition characterized by an accumulation of pus beneath the periosteum, the layer of tissue covering the jawbones. This abscess typically stems from an infection spread from nearby periodontal tissues or a deep tooth infection.

Unlike more common dental abscesses that develop at the tooth’s root or in the gums, a subperiosteal abscess forms on the bone itself. If left untreated, it can potentially lead to severe pain, swelling, and systemic infection. Immediate medical attention is crucial to manage this condition and properly prevent further health complications.


Causes and Risk Factors for Developing Subperiosteal Abscesses

Though less common than other dental abscesses, subperiosteal abscesses pose significant risks due to their potential to cause severe complications. Understanding this condition’s causes and risk factors is crucial for prevention and early intervention.

Odontogenic Infections:

The primary cause of subperiosteal abscesses is infections that originate from the teeth or their supporting structures. These infections often follow advanced dental caries or failed root canal treatments. This odontogenic infection can spread to the subperiosteal space, forming abscesses.

Third Molar Surgery:

Complications from dental surgeries, especially involving the third molars or other complex oral and maxillofacial surgery, can inadvertently lead to the development of subperiosteal abscesses. Improper sterilization or post-operative care can exacerbate this risk.


Physical trauma to the jaw or face can compromise the integrity of the bone and nearby tissues, providing a pathway for bacteria to invade the subperiosteal spaces.

Pre-existing Dental Conditions:

Conditions predisposing to infections, such as periodontal disease or those that disrupt the normal barrier of the oral mucosa, can increase the risk of developing a subperiosteal abscess.

Immunocompromised States:

Individuals with weakened immune systems, whether due to chronic illnesses, certain medications, or systemic conditions, are more susceptible to developing more severe and widespread dental infections that can lead to subperiosteal abscesses.

Understanding the Complexities of Orbital and Sinus Complications in Dental Health

In oral maxillofacial surgery, managing infections originating from dental caries or other issues within the subperiosteal space can lead to severe and unusual complications. Dental professionals, guided by intraoral examination and standards set by the American Dental Association, often encounter cases where an infection spreads to critical areas such as the maxillary sinuses or, even more alarmingly, into orbital regions.

Conditions such as orbital cellulitis, subperiosteal orbital abscess, and the more dangerous cavernous sinus thrombosis or brain abscess highlight the gravity of dental emergencies. These scenarios, described in journals like “J Oral Maxillofac Surg” and “Pathol Oral Radiol Endod,” require immediate and aggressive treatment.

Typically, the presence of purulent material necessitates the administration of intravenous antibiotics to combat the spread of infection and prevent further complications. These instances underscore the intricate link between dental origin infections and significant maxillofacial issues, marking them as critical areas of concern in dental and medical research and practice.

Symptoms: Recognizing a Subperiosteal Abscess

Recognizing the symptoms of a subperiosteal abscess is crucial for timely diagnosis and treatment. This type of abscess, developing beneath the periosteum of the jawbone, presents distinctive signs that should prompt immediate medical consultation.

Localized Swelling and Redness:

One of the most noticeable symptoms of a subperiosteal abscess is localized swelling along the jawline or beneath the gums, accompanied by redness and warmth to the touch. This swelling may be firm and extend to adjacent areas, causing noticeable facial asymmetry.

Severe, Persistent Pain:

Pain is a predominant symptom, typically intense and throbbing. It may worsen with biting or pressure and radiate to the neck, ear, or other face areas.

Fever and General Discomfort:

As with many infections, a subperiosteal abscess might also be accompanied by a fever and a general feeling of malaise or discomfort, indicating the body’s response to the infection.

Pus or Fluid Drainage:

If the abscess begins to drain, pus or a foul-smelling fluid may seep from under the gumline or through the cheek skin. This drainage can sometimes relieve pressure and pain but also suggests a significant infection.

Difficulty Opening the Mouth:

The abscess’s location near the jawbone can lead to inflammation and pain, which can cause trismus or restricted jaw movement, making it difficult to open the mouth, chew, or speak.

Diagnostic Procedures for Subperiosteal Abscess

Diagnosing a subperiosteal abscess accurately ensures effective treatment and prevents potential complications. Several diagnostic procedures are commonly used to identify this condition and ascertain its extent.

  • Clinical Examination: The initial step in diagnosing a subperiosteal abscess typically involves a thorough clinical examination. A dentist or oral surgeon will assess the oral cavity for signs of infection, swelling, and tenderness and may perform palpation to pinpoint pain and fluid accumulation areas.
  • Dental X-rays: Radiographic imaging is essential to visualize the extent of the abscess and determine its proximity to the jawbone and teeth. X-rays can reveal bone loss, the extent of the infection’s spread beneath the periosteum, and any possible involvement of neighboring teeth.
  • CT Scan: A computed tomography (CT) scan may be performed for more detailed imaging. This helps to provide a clearer picture of the bone and soft tissues, which is vital for planning surgical interventions and assessing the spread of infection to adjacent spaces.
  • MRI: Magnetic resonance imaging (MRI) might differentiate the abscess from other types of soft tissue infections or assess the involvement of connected OMM tissues.
  • Laboratory Tests: Blood tests, that include complete blood count (CBC), can be used to check for signs of infection, like high white blood cell count. These analysis can help evaluate the severity of the infection and the body’s response to it.
  • Aspiration of Pus: Sometimes, the dentist or surgeon might aspirate (draw out) pus from the abscess. This fluid can be sent to a laboratory for culture and sensitivity tests to determine the type of bacteria causing the infection, which guides antibiotic treatment.

Treatment Options for Subperiosteal Abscesses

Effective management of a subperiosteal abscess is crucial to alleviating pain, eliminating the infection, and preventing further complications. Treatment typically involves surgical intervention techniques and pharmacological therapy tailored to the severity and progression of the abscess.

Antibiotic Therapy: Initial treatment often starts with antibiotics to combat the underlying infection. The choice of antibiotic is usually guided by the outcomes of culture and sensitivity assays from aspirated pus, ensuring the medication effectively targets the specific bacteria involved.

Surgical Drainage: Surgical drainage may be necessary for substantial abscesses or those not responding adequately to antibiotic treatment. This procedure involves an incision over the abscess site to allow the pus to escape, which immediately relieves pressure and pain. The area is then cleansed with an antiseptic solution to prevent further infection.

Debridement of Infected Tissue: During the surgical procedure, any necrotic or infected tissue is removed to aid in healing. This debridement is crucial to reduce the load of infection and facilitate recovery.

Supportive Care: Pain management is an essential component of treating subperiosteal abscesses. Analgesics are prescribed to manage discomfort associated with the abscess and surgical treatment. Additionally, warm saline rinses can be recommended to help soothe the area and keep it clean.

Follow-Up Care: Regular follow-up appointments are important to monitor the healing process and ensure the infection has been fully eradicated. These check-ups may involve further imaging studies or treatments if the infection persists or recurs.

Corrective Procedures: In cases where the abscess has caused significant damage to the bone or surrounding teeth, further dental or surgical procedures might be required to restore function and aesthetics. These could include bone grafting or dental implants once the infection has been completely resolved.

Preventive Measures to Avoid Subperiosteal Abscesses

Preventing subperiosteal abscesses is crucial for maintaining oral health and avoiding the severe complications of this type of infection. Effective prevention strategies focus on minimizing risk factors and maintaining excellent oral hygiene to deter the development of infections that can lead to abscess formation.

  • Regular Dental Check-ups: Scheduling regular visits to the dentist for professional cleanings and examinations is essential. These check-ups help identify and treat conditions like tooth decay and gum disease before they can become more serious infections.
  • Prompt Treatment of Dental Issues: Treating dental problems such as cavities, broken teeth, or previous root canal issues can prevent the spread of infection to the subperiosteal space. Never delay treatment for dental pain or abnormalities.
  • Good Oral Hygiene Practices: Daily brushing and flossing are fundamental to removing debris and plaque, which are prime breeding grounds for bacteria. Use fluoride toothpaste and antiseptic mouthwash to enhance your oral hygiene routine.
  • Healthy Diet: Consuming a diet with high vitamins and minerals content supports overall health and strengthens your immune system. Reduce the intake of sugary and acidic foods that contribute to tooth decay.
  • Avoiding Oral Trauma: Be cautious to avoid injuries to the face and mouth, which can prevent conditions that might lead to abscesses. Use mouthguards during sports and other activities where facial injuries are possible.
  • Quit Smoking: Smoking is an important risk factor for many oral health diseases, including gum disease, which can escalate to more severe infections. Quitting smoking will improve oral and overall health.
  • Education on Symptoms: Understanding the early signs of oral infections and seeking immediate care when symptoms appear can prevent the progression to a subperiosteal abscess.

Long-Term Outlook and Management of Subperiosteal Abscesses

The long-term outlook and management of subperiosteal abscesses depend greatly on timely diagnosis and effective treatment. Proper care and surgical management resolve the immediate symptoms and minimize the risk of recurrent infections and long-term complications associated with these abscesses.

  • Regular Monitoring: Following initial treatment, ongoing monitoring is crucial. Regular dental visits should be scheduled to ensure that the abscess has fully resolved and to check for any signs of recurrence. These appointments may include dental X-rays or other imaging techniques to monitor bone healing and detect hidden issues beneath the periosteum.
  • Long-term Antibiotic Use: In some cases, especially where the abscess was extensive or complications arose, a longer course of antibiotics may be prescribed to eradicate residual infection. Patients must complete the full course of antibiotics as prescribed to prevent reinfection.
  • Oral Hygiene Education: Patients should receive comprehensive education on maintaining rigorous oral hygiene practices. This includes right brushing and flossing techniques to prevent future dental infections, potentially leading to another abscess.
  • Lifestyle Modifications: Recommendations might include dietary adjustments to reduce the intake of sugars and acids that contribute to tooth decay, quitting smoking, and reducing alcohol consumption, which can adversely affect oral and overall health.
  • Management of Associated Conditions: Conditions like diabetes or immune disorders that might contribute to the risk of developing infections should be well-managed. Patients with these conditions require close collaboration between their dentist and primary care provider to optimize their oral and general health.
  • Surgical Follow-ups: If the surgical intervention was necessary, follow-up oral surgery might be needed to correct or restore any structural damage caused by the aspect (such as bone grafts for significant bone loss). These procedures help ensure the long-term functionality and aesthetics of the jaw and teeth.

Recognizing and promptly treating a subperiosteal abscess dental issue is crucial for maintaining oral health and preventing further complications. If you suspect you have this type of unusual abscess complication, it’s essential to seek professional dental care immediately to ensure effective management and recovery.
