A coronectomy is a specialized dental procedure that involves removing only the crown (top portion) of a wisdom tooth while deliberately leaving the roots intact. This technique is typically recommended when the roots of a lower wisdom tooth are very close to or in contact with the inferior alveolar nerve, which runs through the lower jaw.
Yes, when performed by an experienced oral surgeon or dental professional, coronectomy is a safe and effective alternative to full extraction. It helps avoid long-term complications related to nerve injury, which can be difficult to treat.
Why Choose a Coronectomy Instead of Full Extraction?
A coronectomy significantly reduces the risk of damaging the inferior alveolar nerve. Since the roots are left untouched, there’s less trauma to surrounding bone and tissue. Patients often experience less swelling and discomfort compared to full wisdom tooth extractions.
The procedure is performed under local anesthesia, so you won’t feel pain during the treatment. Some mild discomfort or swelling afterward is normal but usually manageable with over-the-counter pain medication.
When is a Coronectomy Recommended?
This procedure is most commonly suggested when imaging studies—such as panoramic X-rays or cone beam CT scans—show that the roots are intimately associated with the nerve. Rather than risk damaging the nerve during a full extraction, a coronectomy allows for the safe removal of the tooth’s crown while leaving the deeply embedded roots undisturbed. This approach significantly reduces trauma to the surrounding bone and tissues and often leads to a faster and more comfortable recovery.
What can I expect from the procedure?
During the procedure, local anesthesia is used to numb the area. The dentist or oral surgeon carefully sections the wisdom tooth and removes the crown, making sure not to disturb the roots. The site is then cleaned, and sutures may be placed to support healing. Over time, the retained roots generally remain stable and may naturally integrate into the surrounding bone. In rare cases, they can shift or become infected, but this is not common.
Am I a candidate for a coronectomy?
A consultation with our oral and maxillofacial surgeons, supported by detailed imaging like a panoramic X-ray or 3D scan, will help determine whether a coronectomy is the right option for you. At Seattle Wisdom Teeth, we offer the latest dental technology, such as Cone Beam CT Scans. This evaluation will assess the position of the roots and their relationship to nearby nerves to ensure the safest treatment plan.
