Wisdom tooth extraction has historically sent shivers down the spines of many, conjuring images of painful surgery and lengthy recovery times. However, modern dentistry is continually evolving with novel methods to tackle age-old problems.

Enter the coronectomy wisdom tooth procedure: a technique that promises to revolutionize how we approach impacted wisdom teeth. But what exactly is coronectomy, and how does it differ from conventional extraction?

Read on as we delve into this intriguing topic and unveil the mystery behind this groundbreaking procedure.

What is coronectomy for wisdom teeth?

Coronectomy for wisdom teeth is a dental procedure designed to address problematic impacted wisdom teeth, particularly when there’s a risk of nerve damage with full extraction. Instead of removing the entire tooth, only the crown (the visible part above the gumline) is extracted, leaving the roots intact.

Coronectomy, also known as intentional partial root removal or odontectomy, is an innovative procedure in oral surgery. Rather than removing the entire tooth, this dental procedure focuses on excising only the crown, leaving the roots deliberately intact, particularly when addressing impacted wisdom teeth. Studies, such as those published by “Patel V et al.” in journals like the British Dental Journal, have highlighted the effectiveness of this approach.

This method reduces the chance of injury to the inferior alveolar nerve, which runs close to the roots of lower wisdom teeth, thereby minimizing potential complications like numbness or tingling in the jaw and lips.

When to have a coronectomy for wisdom teeth

When considering dental interventions for impacted wisdom teeth, the decision to opt for coronectomy can be pivotal. A coronectomy, or intentional partial odontectomy, involves removing only the crown of the wisdom tooth while preserving its roots. This approach is particularly beneficial under specific circumstances:

  1. Proximity to the Inferior Alveolar Nerve: A full extraction can risk nerve damage if the wisdom tooth roots are closely intertwined with or lie directly over this nerve. Coronectomy minimizes this risk.
  2. Advanced Age of the Patient: As we age, the density of our jawbone increases, and teeth roots can become more entrenched. In such cases, a coronectomy may pose fewer complications than a full extraction.
  3. History of Complicated Dental Procedures: If a patient has previously experienced complications like dry sockets or infections after dental surgeries, a coronectomy might be a safer bet.
  4. Concerns of Post-Operative Complications: For patients who might be at a higher risk for complications like prolonged numbness or infections, coronectomy can offer a more conservative approach.

In summary, while the extraction of wisdom teeth is a common procedure, choosing coronectomy hinges on various factors. Understanding the unique nuances of each patient’s dental anatomy and health history is crucial to making an informed choice.

Why Opt for Coronectomy Over Traditional Extraction?

The proximity of the inferior alveolar nerve to wisdom teeth roots can pose a significant risk of nerve damage. Traditional wisdom tooth extraction might inadvertently cause inferior alveolar nerve injury, leading to complications like numbness in the lower lip or even the entire lower jaw.

Third molars, commonly known as wisdom teeth, especially the lower wisdom teeth, are often located dangerously close to this nerve. In particular, the impacted mandibular lower third third molars can be challenging. By performing a coronectomy, oral surgeons can minimize the chance of nerve injury, making it a preferred choice for many.

Advantages of coronectomy for wisdom teeth

In the realm of dental interventions for wisdom teeth, coronectomy, or intentional partial odontectomy, emerges as an alternative to traditional extraction, offering several distinct advantages:

  1. Reduced Nerve Damage Risk: One of the primary benefits of coronectomy is its ability to minimize the risk of damaging the inferior alveolar nerve, which can lead to prolonged numbness or tingling in the jaw and lips.
  2. Lowered Complication Rates: Compared to full extractions, coronectomies often have fewer post-operative complications, such as dry sockets, infections, or bleeding.
  3. Preservation of Jawbone Integrity: By retaining the roots, coronectomy helps maintain the jawbone’s density and structure, which can be beneficial, especially in older patients.
  4. Shorter Recovery Time: Many patients experience a quicker and less painful recovery after a coronectomy than a complete extraction.
  5. Avoidance of Adjacent Teeth Damage: The procedure decreases the likelihood of damaging neighboring teeth, sometimes occurring during a full extraction.

In essence, while traditional wisdom tooth extractions are widely practiced, the coronectomy procedure presents a set of advantages that can make it a preferred choice in specific scenarios, ensuring patients receive optimal care tailored to their individual needs.

Disadvantages of coronectomy

While coronectomy, or intentional partial odontectomy, offers several advantages in dental care, it’s essential to recognize its potential drawbacks. An informed decision necessitates a clear understanding of both sides of the coin:

  1. Potential for Root Eruption: Over time, retained roots can sometimes move or erupt, potentially necessitating a future intervention or even a full extraction.
  2. Risk of Infection: Leaving the roots intact might create a pocket where debris and bacteria can accumulate, increasing the risk of infections.
  3. Possible Cyst Formation: There’s a small chance that cysts can develop around the retained roots, which might require further treatment.
  4. Post-operative Pain: Some patients report discomfort or pain associated with the retained roots, which can sometimes be persistent.
  5. Need for Continued Monitoring: Given the potential for complications, patients who undergo a coronectomy often need more regular dental check-ups to monitor the status of the retained roots.

In conclusion, while coronectomy provides a less invasive alternative to full tooth extraction, it’s not without its disadvantages. Patients and practitioners must weigh the benefits against the potential drawbacks to determine the best course of action.

Wisdom teeth coronectomy surgical procedure

The world of oral surgery is vast and varied, but few procedures have garnered as much attention recently as the wisdom teeth coronectomy surgical procedure. Designed as an alternative to traditional wisdom tooth extraction, this procedure is gaining traction for its unique approach and benefits. Let’s dissect this intriguing procedure step by step:

Understanding the Basics:

At its core, a coronectomy removes only the crown, or the visible portion of the wisdom tooth, while intentionally leaving the roots in place. This is a stark departure from traditional extractions, where the whole tooth, including its roots, is removed.

The Surgical Process:

  1. Initial Assessment: The coronectomy procedure begins with a precise assessment, often aided by dental computed tomography, to determine the wisdom tooth’s position concerning vital structures.
  2. Anesthesia: Like traditional extractions, the patient is given local anesthesia to numb the area, ensuring a pain-free procedure. In some cases, sedation may also be administered.
  3. Incision and Flap Creation: Once deemed suitable for the procedure, the oral surgeon makes an incision to expose the wisdom tooth.
  4. Crown Removal: Using specialized instruments, the dentist or oral surgeon carefully separates the crown from the roots, ensuring the roots remain undisturbed and intact. Leaving the roots in place reduces potential post-operative complications, but regular clinical evaluations become crucial to monitor the health of the remaining root structure.
  5. Flap Closure: Once the crown is removed, the gum flap is sutured back, covering the retained roots.

Post-Surgical Monitoring:

While the recovery period post-coronectomy is often less painful than full wisdom tooth removal, patients might still experience some discomfort. The retained roots necessitate careful monitoring, ensuring complications like infections or movement don’t necessitate further surgery.

In summary, coronectomy, which focuses on retaining the wisdom tooth roots while addressing the main dental concerns, is a testament to modern-day conservative dentistry. As with all surgical procedures, patients should consult closely with their dental clinic to determine the optimal approach tailored to their needs.


Coronectomy recovery

The choice to undergo a coronectomy, an alternative to the full extraction of wisdom teeth, often makes patients wonder about recovery. This procedure intentionally leaves the tooth roots intact so the recovery journey can be distinct from traditional extractions. Join us as we traverse the path of coronectomy recovery, detailing what patients can expect and how to ensure a smooth healing process.

Immediate Post-Procedure Experience:

  1. Mild Discomfort: As with any dental procedure, some discomfort can be expected. However, many patients report less pain after a coronectomy than a full extraction, given the less invasive nature of the procedure.
  2. Swelling and Bruising: It’s common to experience some swelling or minor bruising around the surgical site. Cold compresses can help reduce these symptoms.

Guidelines for Swift Recovery:

  1. Dietary Adjustments: For the initial days post-surgery, it’s advisable to stick to a soft diet—think soups, yogurts, and mashed foods. This prevents discomfort and ensures that food particles don’t irritate the surgical site.
  2. Oral Hygiene: Gentle rinsing with warm salt water several times a day can assist in keeping the area clean. However, vigorous rinsing or spitting should be avoided to prevent disturbing the healing site.
  3. Avoidance of Physical Strain: Activities that could increase blood pressure, such as heavy lifting or intense exercise, should be avoided for a few days post-procedure.

The Importance of Follow-ups:

One key component of coronectomy recovery is consistent post-operative check-ups. Given the retained tooth roots, dental professionals must monitor for potential complications like root migration or infections.

In wrapping up, coronectomy recovery, while generally more straightforward than full extraction recovery, does necessitate careful aftercare and monitoring. Following professional guidelines and maintaining open communication with dental care providers, patients can ensure their oral health remains tip-top, even after the procedure.

Is a wisdom tooth coronectomy painful?

A wisdom tooth coronectomy, like any dental procedure, involves discomfort. However, it’s important to note that the procedure is performed under local anesthesia, ensuring the patient feels no pain during the surgery.

Post-operatively, many patients report less pain than a full wisdom tooth extraction, given the less invasive nature of a coronectomy. While mild discomfort, swelling, and some tenderness can be expected in the days following the procedure, these symptoms are generally manageable with over-the-counter pain relievers and prescribed guidelines from the dental professional.

How long does wisdom tooth pain last after removal

After removing wisdom teeth, it’s common for patients to experience some degree of pain and discomfort. Typically, the most acute pain subsides within 2-3 days. However, some tenderness and discomfort can persist for up to a week or slightly longer.

Factors influencing pain duration include the complexity of the extraction, the patient’s age, and individual healing rates. While over-the-counter pain relievers and prescribed medications can alleviate symptoms, any persistent or severe pain beyond the expected recovery timeframe should prompt a consultation with the dental professional to rule out complications such as infections or dry sockets.


In conclusion, the coronectomy wisdom tooth procedure offers a groundbreaking alternative to dental surgeries. This innovative approach, often recommended for an impacted wisdom tooth or those closely intertwined with the inferior alveolar nerve, prioritizes the patient’s long-term well-being by leaving the roots intact. While traditional wisdom teeth surgery focuses on complete tooth removal, a coronectomy addresses the primary concerns of third molars without risking an inferior alveolar nerve injury.

This method reduces the potential for injury to the inferior structures, especially around the lower wisdom tooth. By leaving the roots and focusing only on the problematic crown, patients often experience a smoother post-operative journey, mitigating many complications associated with conventional extractions. As research and clinical studies, such as those by et al., continue to highlight its benefits, it’s clear that coronectomy sets a new standard in oral care.
