Retained root extraction is a common dental procedure involving the removal of tooth roots that remain embedded in the alveolar bone following the loss or extraction of a tooth crown. These roots may be left intentionally during a difficult extraction, may result from trauma or decay, or may simply go unnoticed in the oral cavity. While they may remain asymptomatic, retained roots can pose several complications, including infection, cyst formation, or interference with prosthetic rehabilitation.
This article explores retained root extraction in detail, discussing its causes, indications, clinical assessment, techniques, complications, and post-operative care.
Understanding Retained Roots
Retained roots are fragments of a tooth’s root structure that remain lodged in the alveolar bone following the loss of the crown—either due to trauma, caries, periodontal disease, or during an incomplete extraction. While they might appear to be harmless remnants, retained roots can have significant clinical implications, especially when left undetected or untreated.
Classification of Retained Roots
Retained roots can be categorized based on various criteria:
1. Location
- Maxillary vs. Mandibular Roots: Maxillary retained roots may pose a higher risk of sinus perforation, while mandibular roots may be in proximity to the inferior alveolar nerve.
- Anterior vs. Posterior: Posterior retained roots (especially molars) are more common due to the multi-rooted anatomy and limited access.
2. Origin
- Traumatic Retained Roots: Result from trauma or fracture without immediate dental intervention.
- Surgical/Intraoperative: Roots unintentionally left behind during an extraction due to complications.
- Pathologic: Result from decay or periodontal destruction where the crown is lost, but the root remains.
- Iatrogenic: Errors during procedures such as endodontic therapy, surgery, or prosthodontics.
3. Visibility
- Clinically Visible: The root or its portion is exposed in the oral cavity.
- Submucosal/Impacted: Completely covered by soft tissue or bone, often detected only via radiographs.
Prevalence and Epidemiology
Retained roots are relatively common findings in clinical practice. Studies show that the prevalence of retained roots can range from 3% to 12% of the population, depending on the age group and access to dental care. They are more frequently observed in:
- Elderly populations: Due to neglect, previous incomplete extractions, or chronic dental disease.
- Patients with poor oral hygiene: Especially in underserved communities.
- Populations with limited access to surgical dentistry: Where extractions are performed without adequate instruments or expertise.
Etiological Factors Contributing to Retained Roots
Several clinical scenarios can lead to retained roots. Understanding these helps in anticipating possible complications and refining extraction techniques.
1. Difficult or Incomplete Extractions
Retained roots often result when extraction procedures are complicated by:
- Root ankylosis (fusion to the bone)
- Severe decay making crown grasping impossible
- Narrow or curved roots
- Hypercementosis or root dilaceration
- Root fracture during forceps application
In some cases, especially in public health settings or emergencies, practitioners may leave root tips behind intentionally if removal poses a greater immediate risk.
2. Tooth Fracture Due to Trauma
Blunt trauma, such as falls, sports injuries, or accidents, can result in the fracture of the tooth at or below the gum line. If not immediately managed, the remaining root may remain embedded and eventually become retained without visible signs.
3. Gross Caries or Periodontal Disease
Teeth severely affected by caries may fracture or break off at the gum line, especially in posterior regions. Similarly, advanced periodontal disease can cause the crown to loosen or detach, leaving behind mobile or embedded root fragments.
4. Orthodontic and Surgical Procedures
Retained roots may also occur during or after certain orthodontic or surgical interventions, particularly when forces are applied to non-vital teeth or during pre-prosthetic surgeries.
5. Developmental or Congenital Conditions
In rare cases, retained roots may be associated with developmental anomalies such as:
- Impacted teeth undergoing root resorption
- Retained primary roots in mixed dentition
- Odontodysplasia or other malformations
Radiographic Appearance of Retained Roots
Radiographs are indispensable for diagnosing retained roots. They typically appear as:
- Radiopaque structures: Well-defined remnants of root morphology within the alveolar bone.
- Surrounded by radiolucent lesions: Suggestive of cysts or chronic periapical infection.
- Associated with bone loss: In cases of chronic periodontitis or infection.
- Proximity to critical anatomical structures: Such as the mandibular canal or sinus floor.
Retained roots are sometimes discovered incidentally on radiographs taken for other reasons, emphasizing the importance of routine imaging in dental care.
Biological Behavior of Retained Roots
The body’s response to a retained root varies depending on its condition:
1. Vital vs. Non-vital Roots
- Vital roots may remain dormant and asymptomatic for years.
- Non-vital roots, particularly those associated with necrotic pulp or prior infections, can become foci for chronic inflammation, abscesses, or cysts.
2. Root Resorption and Ankylosis
Some roots may undergo external resorption, where the body starts breaking down the retained structure. In other cases, ankylosis (fusion of the root to the bone) may occur, making removal particularly difficult and risky.
3. Infection Risk
Retained roots, especially if associated with open canals or previous pathology, can serve as reservoirs for bacterial infection. They may become symptomatic later, even after being asymptomatic for years.
Clinical Implications of Retained Roots
Depending on their condition and location, retained roots may cause a range of clinical issues:
- Persistent pain or discomfort
- Infection and abscess formation
- Swelling and sinus tract development
- Cystic transformation (e.g., radicular cyst)
- Interference with denture fit or implant placement
- Compromised orthodontic treatment plans
- Esthetic concerns in anterior regions
In cases where prosthodontic treatment is planned, retained roots must often be removed to ensure proper seating and long-term success of the prosthesis.
Clinical Indications for Extraction of Retained Roots
Deciding whether to extract a retained root is not a one-size-fits-all decision. It requires clinical judgment, radiographic evaluation, consideration of patient-specific factors, and long-term treatment planning. While some retained roots may remain asymptomatic for years, others can become the source of pain, infection, or prosthetic failure. Understanding the clinical indications for extraction is crucial to avoiding complications and maintaining oral health.
Below, we delve into the primary and secondary indications for removing retained roots, supported by explanations and common scenarios encountered in practice.
- Presence of Active or Recurrent Infection
- Pain or Discomfort in the Area of the Retained Root
- Interference with Prosthetic Rehabilitation
- Cyst or Tumor Development
- Orthodontic Considerations
- Esthetic Concerns
- Pathologic Root Resorption or Mobility
- Preventive Extraction in High-Risk Patients
- Growth and Development in Pediatric or Adolescent Patients
- Patient Preference or Anxiety
Presence of Active or Recurrent Infection
Infection is one of the most common and urgent indications for root removal. Retained roots can harbor necrotic tissue or bacteria, leading to periapical inflammation, abscesses, or even cellulitis.
Clinical Signs of Infection:
- Localized swelling
- Pain or tenderness
- Fistula or sinus tract formation
- Purulent discharge
- Radiolucency at the root apex on radiographs
Example Scenario: A 40-year-old patient presents with swelling and pain near the site of a previously extracted molar. A radiograph reveals a retained root fragment with periapical radiolucency and a draining sinus. This is a clear indication for surgical extraction of the infected root.
Rationale: Retaining the root in such cases perpetuates chronic infection, may lead to systemic spread, and delays healing. Antibiotics alone are insufficient without removing the source.
Pain or Discomfort in the Area of the Retained Root
Even in the absence of overt infection, patients may experience chronic or intermittent pain from a retained root. The pain could result from:
- Pressure against adjacent structures
- Local inflammation
- Traumatic occlusion or irritation from prosthetic appliances
- Inflammatory cystic changes
Example Scenario: A patient with no visible swelling reports dull, persistent discomfort in the premolar region. Radiographs reveal a retained root causing slight pressure against the mental foramen. Despite no acute infection, the root is removed to alleviate discomfort.
Rationale: Persistent pain can impact quality of life and suggests ongoing irritation or low-grade inflammation, making extraction a reasonable course of action.
Interference with Prosthetic Rehabilitation
Retained roots can interfere with the placement or function of:
- Complete or partial dentures
- Dental implants
- Fixed bridges or crowns
They may cause:
- Poor fit and discomfort from prostheses
- Unstable bases in dentures
- Bone resorption around the retained fragment, compromising future implant planning
Example Scenario: A 60-year-old patient needs a lower complete denture. However, a retained molar root in the posterior mandible causes an uneven ridge and denture instability. Surgical removal and alveoloplasty are planned to optimize the prosthetic outcome.
Rationale: For predictable prosthetic rehabilitation, the underlying tissues must be stable, free from infection, and properly contoured. Retained roots compromise these criteria.
Cyst or Tumor Development
Retained roots, particularly those associated with non-vital teeth or periapical pathology, can become a nidus for cyst formation. The most common type is the radicular cyst, but others such as residual cysts or dentigerous cysts (in rare developmental cases) may form.
Radiographic Signs:
- Well-defined, often corticated radiolucency around the apex of the root
- Progressive bone destruction or expansion
- Possible displacement of adjacent teeth or anatomical structures
Rationale: Leaving such roots untreated can result in expansion, bone destruction, or, rarely, neoplastic transformation of the cyst lining. Early intervention prevents further complications.
Orthodontic Considerations
Retained roots can obstruct or alter the path of tooth movement, complicating orthodontic treatment.
Clinical Scenario: A 16-year-old undergoing orthodontic therapy has a retained root in the maxillary premolar region that is impeding the distal movement of the canine. Surgical extraction is performed to allow for unimpeded orthodontic progression.
Rationale: Orthodontic success depends on the free movement of teeth through the bone. Retained roots serve as rigid obstructions and may also compromise anchorage planning or tooth alignment.
Esthetic Concerns
While retained roots are usually hidden, in the anterior maxilla, they may:
- Cause gingival discoloration (gray/black hue)
- Lead to soft tissue contour irregularities
- Be visible during a high smile line
- Interfere with crown placement or veneer alignment
Rationale: In highly esthetic zones, even asymptomatic retained roots may be removed if they compromise the visual harmony of the smile.
Pathologic Root Resorption or Mobility
Roots undergoing pathologic external or internal resorption, or those that have become mobile due to loss of periodontal support, often necessitate removal.
Clinical Indicators:
- Radiographic evidence of irregular root surface or shortened root
- Mobility upon palpation or probing
- Associated periodontal pockets
Rationale: Such roots are unlikely to remain stable or functional and pose a risk for future infection and alveolar bone loss.
Preventive Extraction in High-Risk Patients
In some situations, retained roots may not be currently symptomatic but may be removed prophylactically due to future risk, particularly in:
- Immunocompromised patients (e.g., chemotherapy, HIV/AIDS)
- Pre-radiation therapy to the jaw (to avoid osteoradionecrosis)
- Organ transplant candidates
- Patients on bisphosphonates or antiresorptive drugs, where future surgery may carry greater risk of osteonecrosis
Rationale: Preemptive removal of potential infection sources is standard in medically compromised individuals to avoid complications like osteomyelitis or systemic sepsis.
Growth and Development in Pediatric or Adolescent Patients
Retained primary tooth roots, supernumerary root fragments, or fragments from trauma may impact eruptive paths of permanent teeth.
Clinical Consideration: If a retained root lies in the path of eruption of a permanent successor, surgical removal is indicated to avoid impaction, misalignment, or eruption delay.
Patient Preference or Anxiety
Sometimes, despite the absence of clinical or radiographic issues, patients request removal of retained roots due to:
- Concern about possible future problems
- A desire for a “clean slate” before dentures or implants
- Anxiety about having a “broken tooth” left inside
Rationale: While patient preference alone isn’t always an indication, it becomes valid if:
- The removal carries minimal risk
- The root has no anatomic complications
- The patient has been fully informed
Contraindications for Extraction
- Asymptomatic Retained Roots in elderly patients or patients with comorbidities where surgery poses greater risk than benefit.
- Ankylosed Roots Close to Vital Structures: Such as the inferior alveolar nerve or maxillary sinus.
- Lack of Patient Consent or Financial Constraints: When patients choose not to undergo surgery.
Diagnosis and Assessment
Clinical Examination
- Visual and Tactile Assessment: May reveal visible root fragments or sinus tracts.
- Percussion and Palpation: Tenderness or swelling may be noted.
Radiographic Evaluation
- Periapical Radiograph: Helps determine root size, location, curvature, and proximity to vital structures.
- Panoramic X-ray (OPG): Useful for assessing multiple retained roots.
- CBCT (Cone Beam Computed Tomography): Provides a 3D view, especially important when the root is near the sinus or nerves.
Pre-Operative Considerations
Medical History
- Assess for systemic diseases (e.g., diabetes, bleeding disorders).
- Evaluate current medications (e.g., anticoagulants, bisphosphonates).
Informed Consent
Discuss risks, benefits, alternatives, and possible complications.
Pre-Surgical Planning
- Identify surgical approach.
- Choose appropriate anesthesia (local, sedation, or general).
- Plan for flap design, bone removal, or use of surgical instruments.
Surgical Techniques for Extraction of Retained Roots
Extracting retained roots can range from a straightforward procedure to a complex surgical intervention, depending on the depth, location, morphology of the root, and its proximity to anatomical structures. A successful extraction relies on thorough preoperative planning, precise technique, and appropriate surgical tools to minimize complications and ensure complete removal.
This section explores the primary surgical techniques used in retained root extraction and highlights the considerations, indications, and step by step protocols for each method.
1. Simple (Closed) Extraction Using Elevators and Forceps
Indications:
- Retained root is visible above or at the gingival margin
- Root is loosely embedded or surrounded by minimal bone
- No obstruction from adjacent teeth
- No signs of ankylosis or pathological fusion to bone
Technique:
- Anesthesia: Administer local anesthetic with vasoconstrictor for good hemostasis.
- Soft Tissue Retraction: Reflect the gingival margin gently using a periosteal elevator or tissue retractor.
- Luxation: Use a small straight elevator or root tip pick to luxate the root in a controlled manner.
- Application of Forceps: If enough structure is exposed, grasp with narrow or bayonet root forceps.
- Rotational or Buccolingual Movement: Gently mobilize the root out of the socket.
- Irrigation and Inspection: Clean the socket with sterile saline and inspect to ensure no fragments remain.
Pros:
- Minimally invasive
- Preserves alveolar bone
- Faster healing time
Cons:
- Limited to shallow or mobile roots
- Risk of fracturing root tips if excessive force is used
2. Surgical (Open) Extraction with Mucoperiosteal Flap Elevation
When roots are deeply embedded, covered by bone, or difficult to access, a surgical approach with flap reflection and bone removal is often required.
Indications:
- Submerged root fragments with no crown exposure
- Roots with divergent, dilacerated, or hypercementosed morphology
- Failed simple extraction attempts
- Associated with periapical pathology
Technique:
Step 1: Local Anesthesia
Achieve profound anesthesia with regional nerve blocks and infiltration.
Step 2: Flap Design and Elevation
Choose the flap based on location and visibility needed:
Envelope Flap: A horizontal incision along the gingival margin (used for minor exposure).
Triangular Flap: Includes one or more vertical releasing incisions for greater access.
Reflect the mucoperiosteal flap using a periosteal elevator to expose the alveolar bone.
Step 3: Bone Removal (Osteotomy)
- Use a surgical handpiece with round or fissure burs under constant irrigation.
- Carefully remove buccal or crestal bone overlying the root, exposing enough surface to engage.
Step 4: Root Sectioning (If Necessary)
- In multirooted teeth or long single roots, section the root to allow piece-by-piece removal.
- Use a surgical bur to create a groove and then gently split with elevators.
Step 5: Root Elevation and Retrieval
- Use straight, Cryer, or root tip elevators to luxate and retrieve fragments.
- Employ root tip picks or hemostats for small apical tips.
Step 6: Debridement and Irrigation
- Curette the socket to remove granulation tissue.
- Irrigate with sterile saline.
Step 7: Closure
- Reposition the flap and suture (resorbable or non-resorbable depending on case).
- Apply gentle pressure to stabilize the clot and reduce postoperative bleeding.
Pros:
- Allows full access and visualization
- Increases likelihood of complete root removal
- Enables simultaneous curettage and debridement
Cons:
- More invasive
- Requires suturing and longer healing time
- Greater risk of postoperative swelling or discomfort
3. Root Tip Retrieval with Microsurgical and Specialized Instruments
In some cases, particularly where root fragments are small, fragile, or located near vital structures, microsurgical techniques are necessary.
Indications:
- Root tips near the inferior alveolar nerve, maxillary sinus, or mental foramen
- Broken apical third of the root
- Endodontic failures requiring periapical surgery
Instruments and Tools:
- Micro elevators or apical curettes
- Ultrasonic endodontic tips for precision
- Surgical microscope or magnifying loupes
- Periapical microsurgical mirrors
Technique Tips:
- Create a conservative bony window for access.
- Use microsurgical tools to gently tease the root tip out.
- If the root fragment migrates into a sinus or canal, consider a retrieval approach through the adjacent anatomic cavity.
Pros:
- Preserves surrounding structures
- Ideal for high-risk root removals
- Minimizes trauma and promotes rapid healing
Cons:
- Requires specialized training and equipment
- Time-consuming
4. Coronectomy (Intentional Root Retention)
In select cases, particularly when there is high risk to adjacent anatomical structures (such as the inferior alveolar nerve), the coronectomy technique may be used to intentionally retain the root portion and remove only the crown.
Indications:
- Impacted third molars where roots lie close to or wrap around the inferior alveolar canal
- Non-pathologic roots with no signs of infection
Technique:
- Flap elevation and exposure of the crown.
- Sectioning of the crown from the root using a fissure bur.
- Smooth and bevel the root surface 2–3 mm below the bone crest.
- Flush the site and close the flap with primary closure.
- Monitor periodically with radiographs for any signs of infection or migration.
Pros:
- Avoids nerve damage
- Reduced surgical morbidity
Cons:
- Requires follow-up
- Risk of future infection or need for later root removal
5. Transalveolar and Lingual Split Techniques (Advanced Methods)
Used in deeply impacted or posterior roots, particularly when access is limited, and traditional flap techniques are insufficient.
Transalveolar Extraction:
- Involves creating a wide bony window across the alveolus to access the root directly.
- More invasive but gives direct access in difficult extractions.
Lingual Split Technique:
- Used in posterior mandible when buccal bone is thick.
- Controlled fracture of lingual cortical plate to access the root.
Note: These techniques require advanced surgical skill and careful anatomical knowledge.
Additional Surgical Aids and Tips
Radiographic Guidance
- Use periapical radiographs or CBCT to localize the root and plan access.
- Consider radiographic markers during surgery to confirm complete removal.
Avoiding Root Displacement
Excessive apical pressure may push the root fragment into:
- Maxillary sinus (in upper molars)
- Mandibular canal
- Soft tissue spaces
Use gentle, controlled movements and appropriate root tip forceps to minimize this risk.
Hemostasis and Wound Management
- Control bleeding with pressure, hemostatic agents (e.g., Surgicel, bone wax).
- Avoid overpacking the socket.
- Ensure primary closure with tension-free sutures when possible.
Post-Surgical Radiographic Evaluation
A follow-up radiograph should always be taken to:
- Confirm complete root removal
- Evaluate for retained fragments
- Assess proximity to anatomical landmarks
Complications of Retained Root Extraction
While retained root extraction is often a routine dental surgical procedure, it carries the potential for local, systemic, and anatomical complications—particularly when roots are deeply embedded, located near vital structures, or associated with pathology. The complexity of the procedure, the condition of the root, and the overall health status of the patient all contribute to the risk profile.
This section outlines the possible intraoperative and postoperative complications, their etiology, and appropriate management protocols to help minimize adverse outcomes and ensure a successful surgical recovery.
Intraoperative Complications
These occur during the procedure and can influence the outcome of the surgery or increase postoperative morbidity.
- Fracture of the Root Tip
- Damage to Adjacent Teeth or Restorations
- Oroantral Communication or Perforation (Maxillary Sinus Involvement)
- Nerve Injury (Inferior Alveolar or Mental Nerve)
- Root Displacement Into Adjacent Spaces
- Excessive Bleeding (Hemorrhage)
- Fracture of the Alveolar Bone
Fracture of the Root Tip
Root fragments may fracture further during extraction, especially if:
- The root is brittle due to endodontic treatment
- It is hypercementosed or curved
- Excessive force is applied
Risk Factors:
- Inadequate visibility or access
- Use of inappropriate forceps
- Thin or calcified roots
- Ankylosed roots
Management:
- Use fine elevators and root tip picks to retrieve remaining fragments.
- If the fragment is <2 mm, asymptomatic, and in a difficult or risky position, consider leaving it and monitoring radiographically.
- If left in place, document and inform the patient.
Damage to Adjacent Teeth or Restorations
Excessive force or improper instrument use can fracture or luxate adjacent healthy teeth, damage crowns or bridges, or dislodge fillings.
Risk Factors:
- Crowded dentition
- Close approximation of roots
- Use of broad elevators without control
Prevention:
- Use of controlled, gentle luxation.
- Protect adjacent teeth with a finger rest or rubber dam clamp if necessary.
Oroantral Communication or Perforation (Maxillary Sinus Involvement)
Extraction of retained roots from maxillary molars and premolars may create an unintended communication between the oral cavity and the sinus.
Signs:
- Sudden entry of instrument into a “hollow” space
- Nasal regurgitation of fluids
- Whistling sound during breathing
Management:
- Small communications (<2 mm): Usually heal spontaneously.
- Moderate (2–6 mm): May require suturing and use of collagen plugs or sinus sealants.
- Large (>6 mm): Require surgical closure via buccal advancement flap or palatal rotational flap.
- Prescribe nasal decongestants and instruct patient to avoid nose blowing.
Nerve Injury (Inferior Alveolar or Mental Nerve)
Surgical trauma near the mandibular canal or mental foramen can lead to sensory disturbances, including:
- Paresthesia (tingling)
- Hypoesthesia (numbness)
- Dysesthesia (painful sensation)
Common Sites:
- Mandibular molar and premolar roots
- Lingual cortex fractures
Prevention:
- Preoperative radiographic mapping (preferably CBCT)
- Gentle technique with minimal apical pressure
Management:
- Most cases are temporary and resolve in weeks to months.
- Prescribe vitamin B-complex (neuropathic support).
- Refer to oral surgery or neurology if symptoms persist beyond 3 months.
Root Displacement Into Adjacent Spaces
Types of Displacement:
- Maxillary sinus (most common)
- Submandibular space
- Pterygopalatine or infratemporal fossa
- Floor of the mouth
Causes:
- Overuse of apical force
- Fragile cortical plates
- Root morphology (slippery or conical)
Management:
- Small fragments may be left temporarily if asymptomatic but should be monitored.
- Referral to an oral surgeon for retrieval may be necessary.
- For sinus displacement, consider functional endoscopic sinus surgery (FESS) if inaccessible.
Excessive Bleeding (Hemorrhage)
Causes:
- Injury to blood vessels (e.g., greater palatine, mental, or lingual arteries)
- Systemic bleeding disorders (undiagnosed hemophilia, thrombocytopenia)
- Anticoagulant or antiplatelet medication
Management:
- Apply direct pressure with gauze for 15–30 minutes.
- Use local hemostatic agents (oxidized cellulose, gelatin sponge, tranexamic acid).
- Suture and compress the flap firmly.
- For uncontrolled bleeding, refer immediately to emergency care and consider systemic coagulopathy testing.
Fracture of the Alveolar Bone
Most Common Sites:
- Buccal plate of anterior maxilla
- Lingual plate of mandibular molars
Causes:
- Excessive buccolingual force
- Thin or atrophic alveolar ridge
- Ankylosed root
Management:
- Smooth sharp bony edges (alveoloplasty)
- Reposition loose bone if possible
- Protect area with a soft tissue flap and suture
- If the bone segment is mobile and non-viable, remove it conservatively
Postoperative Complications
These may manifest days to weeks after the procedure and require patient compliance and close monitoring.
- Alveolar Osteitis (Dry Socket)
- Infection (Local or Systemic)
- Trismus (Limited Mouth Opening)
