An Alternative for Selected Lower Wisdom Teeth
A coronectomy is a surgical option that may be considered when the roots of a lower wisdom tooth sit very close to the inferior alveolar nerve, which provides feeling to the lower lip and chin. The crown of the tooth is removed while the roots are intentionally left in place, which reduces the amount of work needed near the nerve.
Coronectomy is not right for every wisdom tooth. Dr. Johnson evaluates the tooth, the surrounding anatomy, your symptoms, your imaging, and your overall health before recommending this approach.
Why Coronectomy May Be Considered
The inferior alveolar nerve travels through the lower jaw. In some patients, the roots of a wisdom tooth develop immediately next to or wrapped around this nerve. Removing the entire tooth may increase the risk of temporary or, less commonly, lasting numbness or altered feeling in the lip and chin.
For selected teeth, leaving the roots in place reduces the need to work in the area immediately surrounding the nerve.
Evaluation and Imaging
A panoramic X-ray is commonly used during evaluation. CBCT imaging may be recommended when the relationship between the tooth and the nearby nerve needs closer assessment.
Who May Be a Candidate?
Coronectomy may be considered when the crown of a lower wisdom tooth needs to come out, but the roots appear to have a high-risk relationship with the nerve. The tooth and the retained roots must also be otherwise suitable for this approach. Coronectomy may not be appropriate when there is infection or disease involving the roots, when the roots are loose, or when another condition makes leaving the roots undesirable.
What Happens During a Coronectomy?
During surgery, Dr. Johnson removes the crown of the wisdom tooth and reduces the remaining tooth structure so the retained roots can heal beneath the gum tissue. If the roots become loose during surgery or cannot be safely left in place, complete removal may become necessary.
Anesthesia
The right anesthesia plan depends on the expected complexity and length of surgery, your medical history, and your individual safety. Dr. Johnson will review the recommended approach during your consultation.
Recovery
Recovery after coronectomy is generally similar to recovery after wisdom tooth surgery. Swelling and soreness often increase during the first two to three days and then gradually improve. The first four to five days are typically the most demanding part of recovery.
Patients should avoid heavy lifting, strenuous exercise, and other vigorous physical activity for about one week unless Dr. Johnson gives different instructions.
Follow-Up After Coronectomy
The retained roots are monitored after surgery because they can shift position, particularly during the first one to two years.
Dr. Johnson may recommend periodic examinations and panoramic X-rays during this period. How often depends on the position of the roots, whether they are moving, and whether there are symptoms or other concerns.
Once the roots have settled into a stable position and the surgical site remains healthy, ongoing monitoring can usually continue with your general dentist as part of routine dental care. Re-evaluation is recommended if the roots become exposed, painful, or infected, or if concerning changes appear.
Potential Risks
Potential risks include pain, swelling, infection, dry socket, delayed healing, movement or exposure of the retained roots, a future need to remove the roots, altered sensation, damage to nearby structures, and conversion to complete tooth removal if the roots cannot be safely left in place.
Frequently Asked Questions
No. In a coronectomy, keeping the roots is intentional and planned before surgery as a strategy for selected high-risk lower wisdom teeth.
Yes. Some movement can occur, especially during the first one to two years. In many patients the roots stay covered and cause no symptoms. If a root later becomes exposed or symptomatic, it can be re-evaluated.
No. Many retained roots cause no problems and can simply be monitored. Additional treatment is considered if symptoms, exposure, infection, or other concerning changes develop.
